sorry but thats plain horrible performance wise and those images are needed
as soon as the gui is opened. So there can be no lazy loading for them. The
total size for all the 60 images is 530kbs . What would happen if I did
some serious animations of 10s of mbs , I will have to go to buy a coffee
to get my GUI opened :D
