Okay I've been getting some help with making icons and I was hoping I wouldn't need to ask for help again.
well I was totally wrong...

Anyway I've been following THIS tutorial and I've did every single step and my icon turns invisible.

now I'm using Adobe Photoshop 6.0 so when I try to save the icon in RGB format it forces me to use 24-bit (which ZiNgABuRgA's RCO Editor doesn't support)
so I make the image an index format and save it as an 8-bit bitmap. (because photoshop forces me to)

so does this technique only work when making 32-bit bitmaps or am I doing something wrong or what?

many thankings are in the advanced.
