I use Photobucket extensively, an image hosting and video hosting website which among other features allows you to edit, crop and re-size pictures. It offers free and subscription based accounts. Free account users receive 2 GB of storage for photo and video uploads, 10 GB of bandwidth for sharing and linking, and unlimited access to Photobucket’s editing and slideshow features.http://s1293.photobucket.com/
Also how can users best minimise bandwidth usage of the forum? Is pasting images a bad move? Can images be automatically resized by the forum software? Can it display externally hosted images automatically resized?
