Image handler 2 has worked perfectly well for me so far, and it's a great addon!

Recently I've added some addition pictures for some of my items, and have FTP them into the same image folder, and named them image-001.jpg, image-002.jpg, etc

My original file was called something different. When I replaced the orginal image with the new one (through image handler admin), I expected the others to show up as well (as I'm sure worked before), but I can only see the original one (in admin and in the shop listing). It does not seem to pick up the others files. Any idea how to fix this?

I have a lot of files to do this way, and FTP is obviously a much quicker way than adding then in manually.

Thanks a lot!
