I tried last night and mine changed...
I doubt this will help, but I bet the first thing you'll be asked to do is clear your cache, cookies, history et. al. and/or do a "forced refresh" to see if that works. Clearing your history/cookies/cache should be an option under "tools" in your internet browser. CTRL + F5 should be the command for doing a "forced refresh". If that doesn't work, it will help the GBS.com folks help you faster if you include what type of browser you are using...I dunno...It could also be the type of file (jpeg, gif, bitmap etc.)...you could try saving the photo in a different format than it currently is in and see if that fixes the problem...but like I said...I don't know that any of this will help. At least it gives you something to try though whilst you wait for help from GBS.com.
All men dream, but not equally. Those who dream by night in the dusty recesses of their minds, wake in the day to find that it was vanity: but the dreamers of the day are dangerous men, for they may act on their dreams with open eyes, to make them possible.
