I'm sure you have thought of it, but consider (again) things like:
Slightly smaller images.
Fewer colors (for GIF/PNG)
Lower quality/resolution (for JPEG)
If you can chop the image file size down, even a little, it may help
Maybe consider posting your image generation code -- Frequently
there's a faster way to do something on that for incredible
performance boost. Though, again, I would assume you've already been
over this with a fine-tooth comb...
Still, you never know.
If the information page is a lot of text, maybe gzip it, if you can
specify the browser at a level that will support zipped content. This
will only matter if there's a fair amount of text there...
gzipping the images probably won't help.
