I just made a screen dump to illustrate the above, I opened the two sRGB files in PS, the one with the embedded sRGB I let open using the embedded CS, the one without I applied my monitor (device) CS profile. I then opened the web page in my Browser and placed it on top of the PS window, I then made a screen capture which I pasted into PS using my monitor profile, cropped it, converted it to sRGB and posted it to my web site. http://home.swiftdsl.com.au/~distudio/temp/colourspaces.jpg (~275kB) What can be deduced from this image is that my Browser fails to display the files with embedded profiles correctly and when the Browser view is compared to the file imported into PS as sRGB (bottom left) it's very slightly less saturated than the file imported using the device profile my Browser doesn't actually even render sRGB correctly. If I wanted it to render sRGB correctly in my Browser I'd have to compromise on my whole systems colour calibration by calibrating my screen to sRGB. So if I want to properly scrutinize any image I down-load it and open it in a colour aware application.
