Keeper and dice tower icons

Hi,
using this thread and the extension in it https://www.fantasygrounds.com/forum...ortrait/page11, i managed to change the keeper icon in the chat.
It seems to work ! Now i want to change the dice tower, using those nice images : Attachment 45635 Attachment 45636
Can somebody help me with that ? It is really boring to change manually the images every time i update FGU, thanks !

After some work i managed to create my extension. It change all the tower and keeper icons! 2 hours of work... i'll never be a coder :-)
