Interesting, I have executed quite a few experiments myself (as has David Mann
of this forum) and found that only a Mac Browser was colour space aware, no
Windows browsers have integrated colour management. I do however always convert
my images to sRGB (but strip the embedded profile) prior to posting for web
view but that's only because my editors default working space isn't sRGB.
Which Windows browsers did you observe to utilize the embedded profile? I'd
like one that was CS aware.
I tested on WinXP Professional using MSIE, FireFox, Netscape and Opera. I tested on Mac OS X using Safari, MSIE, Netscape, FireFox, OmniWeb and Opera. All latest versions. I had two Windows systems and displays to work with, and three Mac OS X systems and monitors to work with. All monitors were calibrated using the Gretag Macbeth Eye On Display unit, Mac OS units to the native 1.8 gamma and Windows to the native 2.2 gamma.
On both platforms, rendering varied quite a bit with an image converted to sRGB and then stripped of its profile: Windows browsers varied more than Mac OS X browsers. The same image, with the profile embedded, imaged identically on all the Mac OS X systems and nearly identically on all of the Windows systems ... small variations particularly between Opera and FireFox. Rendering of the jpeg with embedded profile were much more consistent between Mac OS X and WinXP despite the monitor gamma differences too.
I don't know which browsers on Windows are supposed to support color management. Nearly everything on Mac OS X will support color management if they use the OS image display routines, and most do. The rendering difference between embedded and non-embedded profiles was quite clear on both platforms, however.
There is an option in Save for Web to retain the profile.
