HPI Image Format Support for Panels/Pictview

This format is used by hemera and their clipart collections. From the link below: Any HPI file consists of a fixed 32-byte header which resembles the header used in PNG (Portable Network Graphics) files. Following this header, the color image information is presented in JPEG format.
I have created in the past, converters (using PHP) but would prefer to keep the HPI files intact in their normal format. If this format could be added to the thumbnail viewer for panels and the pictview plugin, that would be awesome.
Here is the link:

FYI xnView Professional supports this format, as do other products I am sure. Thanks!
PS: If you want the source for the converter I rolled (it's PHP format) I can provide it.

Awesome. Thanks so much. I always knew you guys were code-gurus and this not only confirms my theory but proves unequivocally that you dont use any non-original code or libraries common in other devteams (besides the actual file format specifications which you must use).
Jan, you also code eroica yes? I would like the full features in my SS for that system, is it possible that the plugin could be registered for SS? I would like to pay for your support/time, and I use eroica features often.
