However if your versions are, in your view, better quality then there is no problem uploading them as they are not true duplicates. Digitally identical duplicates should be rejected automatically at upload as the files have matching SHA-1 checks.
Thats from normal upload. Gwtoolset may be different. Anyways they can be dealt with after the fact too if they are exactly identical as its easy to detect later.

This can be highly useful when re-running uploads as a check of matching filenames or image page text is a lot less processing/data volumes than downloading the image file to create SHA-1 values.
