Do you re-size the pics to a maximum of 800 x 600 before up-loading Rob?
It just puzzles me why it only seems to happen with your pics, and sometimes the odd pic, normally from a new member, or one who uses an image-hosting site. It means I have to wait until the pics load, or be patient whilst I'm able to get 'down the page' to the reply box, every time I open the post. I'm just trying to eliminate possibilities, in case I have a problem with my computer, as no one else seems to mention a problem, but then, I don't see this happening anywhere else.
