I think that here IJ confuses chopping part of the name off because there is a
"-"+number+"." in the title. So IJ thinks that this is the counter of the
replicated image.

It does add the -1, -2 to the original title if the last character is not a
number lilke: Colli-02a.tiff -> Coli-02a-1.tiff and so on.
I guess that this is to avoid adding -1 each time and increase the number
Otherwise it would be  Coli-1.tif, Coli-1-1.tiff and somehow there is a need
to keep increasing the counting.

Aa simple workaround, one can use "_" instead of "-" in the name.
I try to avoid spaces + - and [ ]  in the names because I always have the
feeling that passing names around in macros will cause problems.

Something related: when a plugin creates a new image whose name already
exists, there is a <1>, <2> etc added to the title. However, when one calls
other plugins that use a list of images, llike the Image Calculator these
appear without the <number> and it is guesswork which one is the right one.
The creation order seems to be preserved in the list, but as I said, it would
be useful if the list showed the appended <number> too.
I can't remember if the menu Window lists names with or without the <number>.
I hope this can be resolved too, if it does not.
