I am having a similar issue

[ERROR][Bot #1][07/26 03:02:52 PM]: Failed to load image for selected script, using default image
I've tried reinstalling everything and tried it on 3 different computers. It happens even when I try to login manually. I login in, start the script, and it says the above. I have a feeling that it is on the client side but I wanted to make sure. I had the same issue last night with my zulrah script but everything seems fine witrh that now.
