We have a computer set up for each browser, with all settings set as default. We have an art site so the graphics have to keep to their original proportions and not be distorted. I set the height at 150 pixels and width at %. Worked beautifully in Firefox but IE7 shows the image at about 1 pixel wide. I have set the standard sizes back to a fixed size which is leaving much of the art distorted. Here is the gallery, http://www.galleryonshow.com/shop/Any ideas?

This is just a thought, but if your image paths are coming from a database, isn't it going to be a lot easier to make them the same size? Say 120px square. Then you resize the thumb until it's larger dimension is 120px and layer it on to a 120 x 120 (white in your case) background, merge the layers and off you go. There are other ways, but this has to be the easiest. In my case I use a script that rounds the corners with three different layers and saves it in the correct directory at about a half a second a pop (PSP). Used to take 15 mins. I think it added a year to my life... which I can use to accumulate quality backlinks apparantly.

If it makes you feel any better its distorted in Firefox too.

Maybe you can thumbnail the images before hand ?

That's what I'm thinking. If you make the thumbs before hand, as M1 suggests, you can crop a tiny bit to favor the focus of the image, tweek the lighting and colors to be truer to the real image and experiment with different settings to get better looking thumbs. If they are produced all the same size, there won't be any surprises.

Most of the rest of us don't have art sites, but we still don't want distorted images
