I know I did a trial and error thing and fiddled with sizes but when uploaded them to wikipedia they looked bigger and less clear Its probably not a good idea to boost the px too much We can get away with it at px but as I didnt have any experience in it I had to see what was best I actually have two packages Photo Impression  which Ive been using and Paint Shop Pro  The great thing is that we can crop some images for film premieres and put them in the release section of the film articles
