There's some information about creating new inventory sprites in LoG1:

(under the heading "Using Custom Graphics")

Does this information apply to LoG2 as well?
- Is the size for an inventory sprite also 75x75 in LoG2?
- "Mipmaps should be used with all textures" <-- even for inventory graphics?
- "user interface graphics, such as item icons, should be left uncompressed (use D3DFMT_A8R8G8B8)" <-- does this still apply in LoG2?
- Can inventory graphics have an 8-bit alpha channel or just 1-bit?

The rules for creating item icons have not changed. 8-bit alpha should be used.
