Adding images to wiki is too complex
As I understand, the unique way to add images to a wiki page is by checking it out and back to bitbucket. This can be a simple task for a developer but not for non-developers. For example: product owners discussing application features can be non-developers. This discourages me to use the wiki at all and I have to use another friendlier wiki service. Adding images to a wiki pages should be as simple as adding images to a bitbucket issue. There should be an "Upload image" or "Upload file" when I edit a wiki page online.
