With the emphasis on "almost" :( .ico's have a very different header than 
.bmp's and the image data actually contains two bitmaps, an AND plane and an 
XOR plane, so icons can have opaque, transparent and inverted-background 
pixels. Also, a signle .ico file can contain multiple icons (usually used to 
store multiple resolutions/colour depths). As I worked a bit with .ico 
reading/writing in Windows I volunteer to try myself on an import-filter.
