Uploaded screenshots should use the filename as the default caption. Currently, screenshots have no default caption.
It would also be nice to detect when a file with the same name is uploaded and 'auto-detect' a revision of the file, maybe prompting the user for confirmation on a replacement. However, graphic revisions should be considered as a workflow of their own and include other enhancements.
What version are you running?
1.5.2
