I’ve noticed one minor limitation when adding a custom thumbnail to a file. It doesn’t seem possible to add a GIF file as a Custom Thumbnail, only a static image such as JPG and PNG. I’m storing a lot of videos and adding an animated preview to them would be fantastic. No matter what, I’m very happy with the program.
Yeah, we only support JPEG and PNG for thumbs. Indeed, GIFs are animated in-place but this is because Stagsi reads the actual file data, not its thumb (you will see that in the database there is tXXX.jpg or tXXX.png, not tXXX.gif). So thumbs can’t be GIFs.
Animation is more or less a hack ATM so this will surely change in the future, such as to allow plugins supply animated thumbs.
