I've been asked if my pictures are too big for the sight as they have to shift the picture to see the whole thing. They fit the screen on my computer just fine.
My monitor is 16" (diagonal) and your picture/text above shows well.
Some of the larger pictures do not fit well.
This is a 640x480 pic:
This is same picture an 800x600 and is about the max size my monitor handles.
1024x768 wraps around a bit, but can shift display to the left and get most of the dialog & pic.:
Edit to add full width dialog to see how much wraps around. You can reduce display w/the mouse wheel while holding control key but the text gets pretty small. I can view all text and full picture on the 1024 by shifting display to remove the left hand margin (avatar, name, etc.)
