Images - Maintain height width ratio

[esearing]

How do I maintain the height and width ratio in a thumbnail image when I have multiple images with differing ratios (some tall_and_skinny, some short_and_Fat).

I am calling the image name from a database and outputing it on a new page as a thumbnail.

<img src=&quot;ImageName&quot; height=&quot;150&quot; width=&quot;150&quot;>
does not work because it distorts the image.

PS I do not want to create two versions of the image since I will be managing thousands of images.

The most practical way I can see to do this is to create another field in your image table that holds the height/width ratio value. Your script can then take that and calculate the appropriate size parameters for the image.

You could try to find a COM component that can open the image and extract the properties. Someone somewhere probably has encountered your problem and solved it that way.

Making thumbnails yourself in Photoshop is the preferd way to handle your situation since having the browser resize the images causes some loss of quality.

Does anyone know how do you obtain the size of the image with out opening the image. Can you just get the width and height of the image using something like FileSystemObject?

Thanks in advance.

Yes, you can do this by using a component which your host may have...the two most popular are ASPImage and ASPJpeg (
