@fredde - sorry, IH is not designed to work that way...the 3 sizes are of one image.

@webrob - admin > tools > Image Handler ...IH admin, clear image cache. If you can't, you FTP to your bmz_cache directory and delete everything INSIDE the category. These are the "on-the-fly" images created by IH and will be re-generated as required.

Then uninstall-reinstall IH.

Your images will remain untouched in your imaqes directory.
