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

your are loading 0-59 images in one turn. this takes ~ 1000 ms. Thats not bad.

How about loading them only on demand? This may cut down the start up time:

attache a small change for get and put the images into a dictionary and only load new
"xx seconds-image" when it is used for the first time.
