I think it should be noted that it is a good idea to keep the picture widths no more than 800 pix. The reason I say this is that wider pictures make it impossible for some to see the whole image without scrolling horizontally and it makes all the text on the thread s t r e t c h out to match the picture making it impossible to read without scrolling both up/down and across. This of course is not a rule but sure makes the thread more enjoyable and the pictures more interesting... and less likely to cause motion sickness.
Just my two cents worth.
740 px
900 px
1001 px
1500 px
