Perhaps try altering and saving the picture in another picture editor will see if that is the problem. Presumably the jpeg information is not being completely saved. Some photo editors can save jpegs as progressive scans for web site work. The downloading is enhanced for slower connections as the picture first shows in rough form then improves as the download completes. Dont know if this is what is happening but might be worth looking to see if that option is checked on your image editor.
I've attached a picture saved with progressive scan turned on to see if I can replicate your "problem" ...............Guess not. (sorry)
Hey Andy's looks lovely. What you meant was Malky's Barndoor affair. If not well you should have I after all have posted the bogugly.gif on occassion just to show how ugly a GS can be.
Andy80F - How did you get a flight to the moon to take that pic ?
