Convert Image with different size suffix

Is it possible when images are resized to change the format of the file suffix? Currently it uses -32x32 for instance, I use tools which use the filename as identifiers in code files, the '-' is interpreted as minus, I would like to change the default to something else such as '_'


The size suffix is optional, so you could turn it off, with the further option of specifying a different name for the output file as desired.

Example from the manual:

Image CONVERT=jpg AS=thumbnail.jpg WIDTH=128 HEIGHT=128
