[ic] Interchange should make thumbnails

[tom friedel]

It could use Netpbm utilities to resize an image when it is upoaded.   
I've done that in the custom shopping carts I've written.  I think 
thumbnails are best as jpegs as most people have truecolor displays (as 
opposed to 256 colors). 
The code I have converts to 'pnm', calls pnmscale, and then calls 
ppmtojpeg (for example).  If I had more time I would undertake this.  If 
anyone has any questions feel free to contact me.
