Displaying Image At A % Of It's Size
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.

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 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.

if gfxSpex("images/urlogo.gif", w, h) = true then
response.write w & " x " & h

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.

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?

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.

I'm sure I'm missing something completely obvious, but I can't figure out what. I have a path to an image file stored in a database. I'm trying to align the image to the right, but nothing seems to be working:
Response.Write("<img src='" & rs("faculty_link_to_photo") &"'>")
dispays the photo without any wrapping, but when I try the following, the images go all over the page:
Response.Write("<img align=""right"" src='" & rs("faculty_link_to_photo") &"'>")
Can someone tell me what I'm doing wrong?

I have ASP (classic) code that writes out a table and sets the <img....> tag
with a virtual directory source, e.g. src='/test/imghold/xyz.png', and the
images do not appear on the IE page. The code is from a production site
that works fine.
We just duplicated the web site to one named test and now
the images do not display. The IMG item is in a TD element of a table.
Also, I looked at the "view source" of the page and it shows the <IMG
src='/test/imghold/xyz.png'...> just fine. I even tried it with different
images and none of them show up.

I dont know if this is the right place to ask this but I have a database which contains shop details, each of which can have several images associated with it. In the database I am just storing the image paths, the actual images are held on a remote server.
I am able to grab the pathnames from the database and then use the following code to loop through the recordset displaying the associated image(s).
While NOT rs.EOF
Response.Write("<img src=""servernameImages" & rs.Fields(0) & """ width=""150"" height=""150"">")
rs.MoveNext
My question is, in the event of one of the images not being found, it just displays a red cross, is there any way of testing to see if the image exists before I try and display it?

I have a website that we display images we have saved into a SQL Server 2000 database as binary BLOB. This is on a Windows 2003 Server. Just recently (a week ago) this website began to save the images it is displaying on the website as ASP pages in the Temporary Internet Files > IE.Content > Folder.
We have other websites where we use the exact same code and these do not save files on the server when they are displayed.
Here is the code to display the image:
Set rs = objConn.Execute( SQL )
Response.ContentType = "application/octet-stream"
Response.BinaryWrite rs("Product_Image")
SQL is the SQL String to get the image from database
When I add this code:
Response.ContentType = "image/jpeg"
The images still display on the website, but now are saved in the Temporary Internet Files folder as JPG's.

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.

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......
