Smart Thumbs Contact?
 

Does Bepe still provide support? No sign of Godsmack for years.

Is the script still updated?

Version 5.86 released not that long ago, for example to allow for javascript cropping instead of using Flash based picture cropping. It seems to be alive and active.

Also says:
Smart Tube Pro 1.21 released! August 07, 2017

I know that's a different product, but if that one is being updated, it would seem likely to be able to receive support for the other scripts as well.

No response by email from Bepe. Anyone know who to contact?

Did you try a PM through the support forum?
