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?
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 am developing an web application, it should has the function to upload file from client computer. The uploaded file size can be limited within 10 MB.
But I dont know how to check the size of the file on client-side. Server-side size check is not enough, because it can not be checked until the whole file is received while the server resource(cpu,memory etc) is wasted.
is 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?
I want to specify the maximum length of an image the file can upload.If the image exceeds that limit it should show me an error.E.g.; 640x480 pixels.
View Replies View RelatedI'm having a problem with the fact that I want to allow image files to be uploaded to a remote web server, as the hosting package the web site is on is IIS6 and has a default file upload size limit of 200kb. As it's a shared hosting package, the default limit cannot be changed for me unfortunately.
Anyway - i need to check the size of the file being uploaded, so i can notify the user and prevent them getting the default Microsoft error message page. The problem is that I can't implement a server side size check which works, using either Request.TotalBytes or load.getFileSize (with "load" being an object of my loader class). It seems that I can't carry out any of these operations when the file size is too large.
I wnat to upload file in large size ...
View Replies View RelatedI got a script for uploading files that sets its file size limit to 10240kb. The line in that script Code:
Const MaxFileSize = &H100000
has an equal size of 10240kb. Any idea why &H100000 is equal to 10240kb and how do I set it to less or greater than using such hexa type like value?
I'm using the FreeASPUpload script from www.freeaspupload.net. It works good until I attempt to upload files larger than about 10Meg, at which point my server chokes. The documentation says I need to change the IIS upload limit.I've not been able to figure out how to do it in IIS5.
View Replies View RelatedI had my server run win2K SP4 running an ASP site that uses ABCUpload and all was working fine. Today I have found that we can no longer upload files greater than about 4Mb.
I think way back when I set this site up I had to change a setting some where in windows that allowed the site to accept file greater than 4Mb. Does any body know what this setting is and where I can find it.
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 RelatedThe 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?
