What program did you use to do all this, and would you mind explaining in more detail what you did? I'm no modder, but if it's not too complicated I'd be willing to help make some more icons on my own. I benefit from all these mods so much I'd like to be able to help contribute back to the modders.
Seriously, thanks for all your hard work.
I use the GIMP
Basically I just zoom way in and take the freehand select tool and trace the outline of the image that I want. I then trim out all of the elements that I don't want in the image. To recolor everything I use the same freehand select to pick out just the parts I want to recolor, then use the Colorize tool to change the hue. I usually adjust the brightness and contrast after that to make it look more natural and not have hard edges. On most of these I made a layer above the main image with a glassy texture that was the same shap as the recolored portions, and turned the opacity on it way down to get a better bottle-like filter. I merged the layers when it looked right.
After that I resized the bottles down, most inventory icons in Torchlight are 64x96, so I went with those numbers. I had to fiddle with a couple of the ratios to make them not look too distorted. Then I made an image of forty alternating green and purple rectangles, each 64x96 pixels. I made an empty layer above the 'guide' image and selceted each alternating square one at a time and pasted a potion bottle into that space in the empty layer. Then I deleted the guide layer, saved and was done with the image.
In Torchlight, all of the icons images also have an '.imageset' file. This is basically just a text file that says what each icons name is, and where in the image it actually shows up. I think it's pretty adaptive, I used the same dimensions as the existing Torchlight icons, a 512x512 image containg five rows of eight. I think I could have done whatever I wanted there though as long as the imageset listed it correctly. I probably could have made a 64x3,840 pixel image and had forty icons in a vertical row.
The imageset just lists the name of the file, the name of the imageset in general (although I'm not sure why, I haven't used the name anywhere) and then lists each icon by the start coordinate, which is the uper left corner, and the height and width, which is all 64x96 on these. Obviously you can make smaller icons, like the gems, or larger images, like the UI buttons, or character portraits.
The simplest way to do that is just to copy an existing imageset and use the same values with different names.

This is the icon guide I used.
