View RepliesHow can I get the height and width of a jpeg image?
View Repliesi want to write code for downloading Jpeg images from a hyperlink click when i passes jpeg images then browser opens it in the window rather then showing download window
right now the only way through which i m able to perform this is by zipping these jpeg images code is foll.
<A href="images/images.zip">Download images</a>
I am having a problem with this code. The problem I am facing is that
the first image is displayed in its original size. But when I click the
next button, the next image not displayed in its original size, but
being displayed as 100 x 100 pixels, same goes to the 3rd picture and so
on. Code:
I only need to know the height and width of the image.
It doesn't seem to be as easy as php's "getimagesize($imgFile);" method.

Which is a little bit shorter, and seems to work ok so far, but isn't there anything easier, like php's "getimagesize($imgFile);"?
i have a page that displays an image. the image path is a variable passed in the url link. eg. enlarge.asp?picture=http://www.hey/.com/you.jpg
and the window it opens works. but id like to try and get the enlarge as to get the height and width dimentions so i can call a new window to opena popup and ill dynamically have the images dimentions to scale the popup to fit.
and right after the javascript calls a new popup window itll use a close window function. and since it happens before the head tags it should be seamless as if i had a regular link calling a popup.
I have a table full of pictures with urls to images. Any idea how I could find out the dimensions of the images? i want to design tables to show them in a better way.
View Replies View Relatedis it possible to have an asp script create a thumbnail of an image upon upload?
i want to create a rather small thumbnail and 65 x 83 and put it in a folder '/sized'
oh yeah, and one more quick thing.. i am pulling information from a database.. why is it that the symbol ' gets changed to a ? when pulling it from the field.. will this go away when i start adding information through forms instead of access?
The pic in the DB is just a named reference, as all the pics are stored in 2 common folders. 1 for the normal size pics and 1 for the thumbnail equivalents.
As this particular page has to be tight on space, I wanted to set the image as a percentage of it's size so I set the following:
<IMG SRC="thumbs/<%=picname%>' WIDTH="30%" HEIGHT=30%> etc....
Problem I have with this is that the browser seems to set all pics to 1 common percentage size rather than each being say 30% of each individual pic's size. This results in some piccies being completely distorted.
I don't want to go down the route of storing the x and y of each pic in the DB, so could you please let me know if I am doing something really stupid with the above.
My ASP app dynamically retrieves from db and sends JPG images using Response.BinaryWrite(). And it seems work. The script sets image type as "Response.ContentType = 'image/JPEG';"
But viewing image properties in IE returns Type and Size as 'Not available'.
How to set these properties properly?
Is there any routine I can call to reduce the size of an image file after
uploading a file from a client. I am looking to reduce file sizes
programmatically using C# in my web page after uploading. I know that
Photoshop can do it but I need to do it dynamically in my web page. I tried
doing it myself with some of the Bitmap thumbnail instructions but the
resulting image is very bad. I need a file reduction routine that creates a
good image that is smaller. I figured if Photoshop can do it then so can I
but how?

View Replies View RelatedI am writing a little script for an online album. The pictures' size varies
a lot. I have a maxim size for every displayed picture because the layout

the smaller one in their original size. Is there any script or code that
can do this automatically?
How can I use ASP to check the size of the images used in my solution?
This is what I need to do:
If the width of an image is more than 256px, I want to set the image width to 256px. Images that is smaller (ex: 100px width) shall not be adjusted.
I have a couple of images that the user can upload, but I want to limit the size to 512kb(most of them will come from a digital cam).
Is there a way to check the file size before the page submits? ie a javascript function that i can call before submitting the page?
I have an photo gallery, I want to create a button that opens a new window fixing the full size image snugley in it, which is easy.
But I want to get a script which detects the image size so i can use the variables to open the window.
What i want to not do is have to more options in the database with height and width in, and have to call them, although i'll do that if i have to, but i thought i would try something new.

View Replies View Relatedrtf files cause so many troubles,i.e.,allow the users to download the files, slow loading,incompatible with other browser, and so on. Do you think I should convert them to JPEG files to embeb them into HTML?
Once converting JPEG,it is easier to programming in HTML(i.e.,just add the image tag),load faster,and prevent the user from download the files?
I have a JPG file residing on my server with an ASP file. I wish to call the ASP file and have it return the JPG file. I do not want to load the JPG into some kind of ASP Image Processing Object. I just want to return the file.
I have already identified the content type with Response.ContentType = "image/JPEG" but can't get away from this text-only read/write system.
I haven't programmed ASP in years and have since moved onto PHP, so I am having trouble doing some of the basics
I am using Response.BinaryWrite to display JPEG's to the browser. The
problem is that in IE, one particular JPEG is loading very slow. Normal
JPEG's take a few seconds, but this one sometimes takes up to 30 seconds.
THe weird thing is that if I refresh really quick, the JPEG appears for quick
second, and then the new Response.BinaryWrite kicks in. So, it looks like
the browser has the image, but for some reason it is not finishing loading it
into the browser. Code:
Im currently making a photo album website which has an ASP page to look in an images folder for any available jpg images.
What I would like is to extract the jpeg data such as width, height, title, bit-depth, comments etc.
All the fields can be found in windows xp if you right-click the image and then click Properties. Select the "Summary" tab and there is where all the jpeginformation is stored and can be edited.

I have a client who has had a ASP site with an Access database for several years. It stores information for the used cars on his lot. I have stored text in the database that points to the location of the image for each record. Each record will have a thumb image that is supposed to display in a list of vehicles available then the user can select an item from this list and a new page displays with the information and the regular size image. So far everything has worked fine exept for the display of the images which are stored in a separate directory called veh-photos. All I get are image place holders. I am using Dreamweaver 2004 and and Access 2000 for the database.
Following is the code to list vehicles: ....
1.I want to show a image file of type '.tif' in the browser window; for that I'm writting as ASP code page.
2.This '.tif' type image can be shown better with 'Kodak Image Control'.
3.To have this 'Kodak Image Control' on my code page I just add it's ..ocx to tool box and then drag it from 'Toolbox' to the page.
4.Now after dropping this control to the code it's type is getting changed to 'object' instead of type 'ImgEdit'(and I think this is the
reason I don't get correct result).
5.On one button's 'Onclick' event I'm calling a javascript function with which I'm setting a 'Path'and'Display' property of a control.
6.And want to show a image at location -- '..MFTDRCMF919685173-62.tif' which get shown in new browser window but could not get shown in that particular control. That means the path is correct, then what is the problem?
For better understanding of problem I'm pasting a following code which I've tried up till now......

I am creating a dynamic ASP VBScript page, which gets data from an Access database.
In the database, there is a field which holds a URL to an image. I can get the image to display fine, but where there is no file that matches the URL (i.e. a missing image) I want to display an alternative, default image (e.g. one that says "Awaiting Image"). The field is never blank, but the image file may not exist for all records in the database.
I think what I am trying to get to is the following:
If file exists (using URL from database to get location of image file) then
display image using the url from the database as the image source
else
display default image - hardcoded in program
endif
I have had a go and come up with the attached but I get an error with my if statement...
I can convert an image that is retrieved from a FileUpload object into a byte array and insert it into the database..
When the user signs-up i wish tosimply insert into the Picture (DB Type = Image) field to an image i already have saved in my images folder?
Anyone know of a way to do this? Tutorials, articles or advise??!

both methods

I'm working on a project where I'm suppose to upload a image to a server. The uploading works fine but when I want to change the image I uploaded to another image I can't get the filepath of the old image to show in my "filefiled"....is it possible to set a "value" where I can retrieve a filepath in a form if the input type is "file"?
