First off, thank you for this great image viewer/processor. It's quite good and stable on the system.

There do however seem to be a few bugs. The biggest one for me is when doing a simple batch convert without renaming, it fails add the extension to the filename, and my Mac thus has no idea what format the new image is in. The only way around this seems to be to initiate the rename protocol as well, and just add additional numbers at the end of the filename.

Apart from that it does seem to be a pretty great product.

Thank you.
