Hello!
Some question and tips about this good extension.
Testing only with Imgur image storage ID.
1- If go with "BBcode template" all the images upload go with URL LINK. If any one click in the image redirect to imgur.com webpage. If upload with "Mardown image template" no have any url link. Not have possibility to delete the URL link in BBcode ? or maybe optional to select the link?
2- About the links to open the image in full- page view that other similar extension "imgur Upload" have and option in the admin panel to select or no the option to link the imagen to full page, as you prefer. In this case, if you select "with link" the image not open in imgur gallery as view in FoF Upload, open directly in the image url link with *jpg final address and not view any for imgur. The background is completly black. In think is a good tip to implement if it´s possible.
3- I testing other extension: "Imgur Upload by Matteo Contrini" and view that have a good point that not view implemented in FoF upload. In Android mobile devices, if working only with "upload button" in Fof upload when click in the button I have some options: Take a photo with the camera or explore the mobile folders to search the photo. In the Matteo Contrini extensión when click in the upload button go directly to mobile gallery to select the photo you need to upload. I think this option is better when working via mobile device, directly to the gallery.
4- Create and option in admin panel to hide Markdown image button to no duplicate the same action with different icons.
