optimizing transparent images for web

[simeonrun]

i'm building a website, and some of my images are wayyyy too big in file size, but i can't seem to optimize any of the transparent images without losing quality.

any ideas on how to fix the problem?

i'm using photoshop cs and/or fireworks cs4, if that would be any help to you guys!

have you tried .pngs? Though those can run big, too.

or can you make the background the same color as the images?

the files are in png, and i can't make the background the same color as the other images, because they're entirely different things. one's cork and the other is paper. :[
