How to manually edit icons (for filetypes, etc)?

[craigyjack]

Hey,
I was wondering what is an easy way, if there is any, to edit the icons for say the default folders, or mountpoint, or trash? I know icon sets can do this, and I have an icon set, but I would like to be able to go in and manually change icon types (decently easy if possible) for the generic folder icons, or trash icon, etc.

I do not know how to make icon sets, and would rather not. I would rather just edit my current one, and change some icons that I do not like so much, with some images i like more (these are png's). Also, on a side note, their doesnt seem to be all that many icon sets from gnome really (i looked at gnome-look.org and art.gnome.org). And manually editing icons for an entire type of filetype (like mp3s, or folders, etc) isnt that easy, and that surprises me because of the level of customization of the desktops.

If anyone could offer me any help on how to get some of my own chosen icons into the general icons in use, I would greatly appreciate it.

Thanks,
Craig
