I like the new version of the Advanced Attachments plugin a lot, thanks for the added functionality! It really helps with the usability of the forum for my (very inexperienced) users. Only one thing is a bit weird: copy/paste a photo from another website results in two versions of the photo in the post, one full version and one thumbnail (clickable). See screenshot:
This does not happen with other methods of adding photos. Why is this and how can it be resolved? I would like to offer this as a way to add a photo to a post for my users but this is a bit confusing.
