Almost there except that there could be a number of '-' separators in the 
filename such as

2021-schimmel-title-1.png
2021-schimmel-title-2.png
...
2021-schimmel-title-356.png

and the sorting would always occur on the last field.

Additionally I would also like to handle situations like this one

2021-schimmel-title-001.png
2021-schimmel-title-002.png
...
2021-schimmel-title-356.png
