I cannot stress this enough!
If you want your picture of your coin to be the pictorial representative of it's type in the Numista catalogue, then I feel this is an imperative responsibility for you; please, PLEASE, PLEASE crop your photos! Especially (read: most of the time) when you're trying to replace an already cropped photo. It is unfair on the users of the catalogue and whoever has to work on cropping another pair of pictures.
The conditions I look at for deciding if a new photo should replace an old one are 1) if the coin depicted is an example in better condition, 2) if the photo quality is better or worse, and 3) if either is already cropped or not. 1) and 2) are to at least some degree, subjective, and should be up to the referee, but 3) is absolutely non-negotiable to me. I have had a bunch of annoying requests in the past from new users who want to upload their blurry pictures to replace perfectly good ones taken from cgb.fr which absolutely infuriated me; I mean what were they thinking?
So I would like something to the effect of the above to be included in guidelines for editing the catalogue, and given how those offending request-makers probably don't read it too often, perhaps also included below the "upload a new photo" option when editing a coin.
