Just discovered this by accident...
I upgraded to the latest version of Photoshop version CS a few months back. I had version 5 previously, so quite a gap, so maybe this is old news to some of you.
Anyhow one thing you can do now in CS is set up a profile, like if you have a color printer it will make changes based on the hardware. Sounds cool and it is.
BUT...
Something I didn't notice and just discovered by accident. Was doing a little house cleaning on my web site and wondered why the later thumbnails I uploaded to the menu page while the same physical size as the others were much larger in bytes.
Well...
I open an old thumbnail and a new one, one I made in the new version of Photoshop. Along side the new one the option to use ICC # Espon Stylus printer 900 was checked. Not an option on the older thumbnails since they were made in a older version of Photoshop.
So...
Guess what... unchecking the ICC profile and the file size shrunk from a bloated 240K for a tiny 145 x 133 icon down to a little 11K file.
Sure enough I looked at other images I made and put on the web site since my new version of Photoshop and they too were very bloaded. Again, I opened and resaved with the ICC profile unchecked. No change in the actual image, but I saved several millions of bytes.
Duh... I feel kind of stupid. Easy enough mistiake to make I guess. So moral of the story Don't assume, LOOK at the file size when saving, especailly for web stuff when size is so critical.
