Now there's a good idea bumble!! :-)

Re: bigger pictures.

In order to display larger pictures anywhere, a picture of that size would need to exist - ie, everyone who has sent a picture would have to send a new, bigger one. The smaller one then would need not exist, because width and height tags can be added to the image code to shrink it. However, this would only work if the same width to height ratio was used for the larger picture. For example, 80x100 or 160x200 or 240x300 or any other sizes where W:H = 4:5.
