I am setting up an e-commerce app. made in ASP.
I am displaying products description and pictures from the database.
I have the following label:
<img border=0 src="images/<%=pImageCategory%>" alt="<%response.write pCategoryDesc%>">

What I need is to ASP to write the Width and Height property of each image from that label. Every image size is different to each other.

I supose it must be some script to do this.

Many thanks.

Store the width and height of the images in a database. That's the easiest way.

Alternatively, ASPImage could be used to find the width and height (it's free and out there.)

For the record, you'll want to do this before hand, and store the values in the database. You don't want to slow your server down by opening up images just to find their height and width on a per-request basis.

You would want to create a second page that queries the database for a list of images that don't have this information attached, and then ( possibly using ASPImage ) collect it and update that record. This way you do the work only once, and can serve up data much faster to the client. The only trick becomes how to "schedule" calls to this new asp maintenance page.

Thanks for the posting.
Do you know any script in order to fill in the widht and height of the images in the db?
I have been looking around but the ASPImage don't have proper documentation (or at least I don't find it).
Thks again.

There are many ways you can approach this problem to solve.
1. Retrieve the data, loop through to add them in arraylist or somthing like that(you may make an object also before putting in arraylist or so). Dont save the image width/height on DB. When you loop through you can create a Bitmap object (dont remember the exact method something like ImageFromFile..). Now you can use the bmp.Width bmp.Height property on your object (bmp is the Bitmap object)
----------------
I dont suggest this though. If you are creating an e-com solution I suggest you use css for thumbs, and other images. all thumbs should be same size.
You can use css like this:
.imgThumb {width:90px; height:110px;border:0;verttical-align:top;overflow:hidden;}
2. You can use javascript to detect the width/height.
3. You can define your <img> tag like this <img id="img1" runat="server" .....
if you are using asp server control. Then on itemdatabound get the width and height of that image control

Mybe your design just need to have enough space for these images, if you need weight and height just because of your design movings while imgs are appearing? If images have enough fixed in size space your design will not shocked when imgs appear. So in this case you don't have to take yourself in weight and height problem's jungle.
