One can sort those using a numeric sort.
$ sort -t- -k1,1 -k2,2n file1
schimmel-1.png
schimmel-2.png
schimmel-3.png
schimmel-04.png
schimmel-05.png
schimmel-06.png
schimmel-07.png
schimmel-08.png
schimmel-09.png
schimmel-10.png
schimmel-11.png
schimmel-12.png
schimmel-13.png
Or as a non-standard extension use --version-sort.
$ sort --version-sort file1
schimmel-1.png
schimmel-2.png
schimmel-3.png
schimmel-04.png

I say non-standard but it exists in GNU and FreeBSD so that may be
portable enough. But it does not exist on NetBSD for example. So
some caution for portability is required.
