Icon overlays can be used to quickly show that a file has a particular property:
A file can have several overlays, for instead a lock and a green checkbox, in such case the overlays might be dispersed on several corners of the thumbnails so that all are visible.
I need a file explorer that shows:
- A particular overlay (for instance a small Earth globe) when a picture has EXIF geographical coordinates.
- A particular overlay (for instance a puzzle piece) when a picture has already been uploaded to http://commons.wikimedia.org
I realize that the second criteria is a requirement that nobody except me has, so I welcome solutions that allow me to develop my own icon overlays, for instance by coding them in Java or another language. My code must be able to call a web service (there is a fast API to check that criteria from the image's checksum).
Also, the file explorer must show thumbnails of pictures. Actually, it can be a gallery rather than a file explorer, as I will only use the software to browse my pictures.
