What does this error mean?
I get it with the attached PNG. It does create a small button successfully, which is how it is displayed in my toolbar:


Image is too large. Use max 96x96px
Thanks for the quick answer!
Resolved issue. pyRevit now accepts icons of all sizes but will show a warning if larger than 96x96.

Will be pushed with 4.6.7 next week
WHAT?!?!?! You rock!
