Adds cover sticker if needs updating for unsupported host / big size / small resolution
目前為
Context menu entries for all hyperlinks in torrent descriptions to directly set album cover from the link; requires installed Image Host Helper script as backend and setting personal API key (redacted_api_key storage entry); context menu entry probably won't show on most recent browsers as the feature was removed but can be supplied by the features below
Torrent cover can be set now also by Alt + click on any hyperlink inside description areas (works on all browsers, same requirements as above)
If cover is uploaded to unpreferred host, cover sticker is clickable. Clicking it directly rehosts the cover to site's preferred host which is PTPimg for RED (same requirements)
Drag & drop active or inactive webstore link to cover preview box to replace current cover with cover at the link (same requirements)
Drag & drop image from local folder to cover preview box to replace current cover with this image (same requirements)
