1. Dropzone attachment removal, pretty simple replacement 2. Image diff: The previous code fetched every image twice, once via `img[src]` and once via `$.ajax`. Now it's only fetched once and a second time only when necessary. The image diff code was partially rewritten. --------- Co-authored-by: Giteabot <teabot@gitea.io>
