i have to do it the long way. basically if its windows way i use, open the image in paint, select 'image' i think on the toolbar then 'resize/skewer' and scale it to about 50% first then do it accordingly to size. select save image as e.g 'sidehop'. i use photobucket so i click upload, and then copy the 'img url' i think it is onto your topic, select insert image, then paste the img url.
lol bit long winded, but it works.
