I know I've told people to use the img width code and it's still cool but
If you know you're going to be posting several huge pictures, can't you use thumbnails instead? It really makes more sense than posting several huge pictures in a row.
Upload the pictures to a site that creates thumbnails, please. There are many of them out there, including the jphip picroda
http://picroda.jphip.com/ but also imgbox.com (where you can upload several pictures at a time and choose the thumbnail size to your liking)
The width code is better if you have one or two big pictures, not like... 8-12
I shall be editing the image posting guide thread again after this...
