It would be useful to upload images directly into this forum without having to rely on links. I don't think links are as reliable and easy to work with as images that are uploaded directly to the forum.
Images would be a good way to show mockups of features that users think will be helpful. I would like to have the ability to upload multiple images at a time (preferably 10-15 images per post, although usually not that many will be needed) in order to provide good visual examples. Also, it would be best if GIF images are also supported because sometimes an animation can be more descriptive than a still image.
In my opinion, this feature would make the forum better because visuals can improve communication. It would be nice to have, although priority goes to features that will actually improve Artstudio Pro. This is just something that hopefully can be realized in the future.
