...or rather than just giving the solution to you, we can discuss it here so everyone can share. I'd have this as a JSP that created 2 images that get stretched depending on the proportions. eg
You also have the option of scaling or normalising the data (eg if they can only have a total width of 200 etc) In addition, if you make the gifs 1*1, they are tiny but still look the same when stretched. This what you were looking for? Dave
