this has probably been brought up before but Im not known for my searching skills
but basically, I'm talking specifically about images. can they not be larger? such as perhaps 600-700 x 300
not that I would ever personally want one that size but it gives more freedom. for example, I hate having only 500 width as a maker of banners cause the dimensions are quite ugly. just as Im sure someone who wants to post a portrait image would want more room height wise.
anyway, just a thought
