I think it would be a fantastic improvement to allow users of their respective forums, to allow them to upload files supported by their respective software. A .jpg I find is very limiting in that regard.

For instance: a user that was having an issue, could upload the file, and state the problem.

The respondent, could fix the file and attach notes as to the steps he went thru to do what he did. Or he could  make what thought were improvements - i.e. how to improve on the idea the OP was trying to get across.
