jquery - Regex formula for a file name

Question

I would like to allow a field in a form I have to allow only file names to be accepted. File names looks like this:

431714620407606949.jpg

18 digits [dot] jpg/gif/ico/png/tiff

Also I would like the field to accept multiple file name entries, so I want it to be like this:

431714620407606949.jpg,431714620407674859.jpg,837593620407606949.jpg
