Right. I need to make some buttons with rollover images. I was going to use JPEGs, but this makes the file size too big, and does not in any way always work smoothly.
So, should I use GIF or PNGs, for the image files? I have two conflicting onions, with two codey bods I do stuff with. I can't be bothered with their arguments, as neither are really coming up with any conclusive reasons why one or the other.
Enter the infinite wisdom of STW! Any thoughts? Any reason why I should use one, over the other?
With some of the buttons, there will be a little thumbnail, which when rolledover, will reveal a larger version of the pic in another window. Use the same type image file for those too?
Any advice appreciated as always.

- it would probably go even smaller, but I don't have OptiPNG or pngcrush handy on this PC.
