jpeg/png: Remove erased file name from list of file when change file.
Change trivial check of entries (entries is always > 0). Fix bug of r23632 that error message is shown when change file while there is only one file. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@23662 a1c6a512-1295-4272-9138-f99709370657
