Cannot make custom item icons

[KiraImmortal]

i tried also this resize thing, i also saved these images in 60x60, and still got problems with the edges.. so i tested all (you haven't included the key_study.tga, but you said it's working, i trust that), and the bone_saw, inventory_battery, and quest_added.tga-s have white background still :/ thanks for the other ones by the way, you're already mentioned in the credits of my mod if you can fix the others in a short time, that would be very good! please include the key_study also if you succeed
