how to get/make more icons?
 

I'm sure this is a basic question but I can't figure this out... I need some icons for associating with items in the Resco Today plugin for example. The ones I get on the built-in list are kind of weird (they never look like the things I need) and there are relatively few of them. Can someone tell me where (and how) to download a sizeable collection of useful icons (ideally, freeware) or how to make them? What size/format file should I make and where do I put it on the device so that it appears in the list of icons that can be associated with files? I'm using WM6.5 on an HTC Imagio (a high-res touchscreen).

thanks in advance,

Mike
