Rename files

Remove all "unsafe" characters on Unix-like systems, i.e. characters you should quote in shell scripts, and invalid characters on Microsoft Windows:

dio ren -f san *.jpg

Add a prefix like img-640x480. based on media information:

dio ren -f img waterlife.jpg
# waterlife.jpg => img-800x600.waterlife.jpg

Add a prefix like ih-F8F07B7F3F0E0E0F. where F8F07B7F3F0E0E0F is an imagehash

dio ren -f ih lightning.jpg
# lightning.jpg => ih-F8F07B7F3F0E0E0F.lightning.jpg
