Feature requests: attachments, image size

The plugin could be improved with the following two features:
– limitation of minimum image size. Maybe it could be useful to also modify “width” and “height” of the image limits into “long edge” and “short edge”.
– deactivation of specific image formats
– complete tracking of images uploaded with the plugin, from upload to deletion. For example, automatic deletion of image files from the WP library and the server when a photo is removed from a gallery. Second option: establish a link (in some way) of images used by the plugin and the entries in the WP media library, so that the user can clean up the WP media library by himself. Right now the WP media library is unaware of the plugin, so that EVERY image uploaded appears as “unattached” (https://postimg.org/image/1h0wa9740b/).
