Personally, I don't mind large images being posted, as the site can more than cope with the bandwidth etc, but all the smaller versions of the images are generated by the server, rather than being sent as the large file and your browser scale it down, so the larger the image, the more performance is required to display each page. This obviously only applies to attachments on the site however, so while I'd appreciate nothing MASSIVE being uploaded, it's not the end of the world if it is, and links to external images can be as big as you like, but don't put huge images inline as they're hard to see in the forum layout. Far better to have a direct link to the image so your browser can scale it to fit :thumbup
