A quick glance at your gist, I don't think you are using createThumbs() correctly.

I suggest looking at the API for the function createThumbs() api.joomla.org/cms-3/classes/JImage.html#method_createThumbs

It doesn't give you an option to specify a file name, just a folder.

I suggest also looking at generateThumbs() api.joomla.org/cms-3/classes/JImage.html#method_generateThumbs
Which I think might be better suited to your application. You could create you thumbs manipulate the image object to rename the thumbs, then use toFile to write the image to disk in the renamed format. api.joomla.org/cms-3/classes/JImage.html#method_toFile

thanks, i create a git with my solution, maybe is not the better but work for my, the info is in spanish :-S

i hope this help to someone
