prpc image load client module

[TromNek]

I'm working on a variation of Dizzy's 'Load Image Node' client module.

This one will allow the user to create nodes for multiple actors, material zones and poser surface inputs all with one load.
Very handy for large scale scene changes.
I also hope to have some preset material zone selections for uni-mesh characters.

Attached is my current beta.
It currently only supports Poser 6 and .jpg files.
What other file extensions do I need to include?
(jpg, bmp, bum, gif, tif, png, psd)

I'm looking for feedback on it for development. In particular, what kinds of options should I include for connecting and deleting nodes?
Initially, I want to keep the options simple. However, I don't do alot of fancy node work, so I need some advice on what options people consider essential.
