Problem with phpthumbon, add ad to filename, how to remove it?

Question

MODX

Greetings!

I ran into a problem:
I change the size of pictures using phpthumbon, everything is fine, but it adds characters to the title. Often, for some reason, ad is added, and these pictures are cut by ad blockers.

Example, it was - became:
cobmr3.png - cobmr3_450x300_b0c.png
e095yl.jpg - e095yl_450x300_ad5.jpg
dre4h7.jpg - dre4h7_450x300_ad5.jpg

How to forbid adding the last 3 characters or make them numeric?

Answer 1

In the phpthumbon.make_cachename system variable, specify the name of the snippet in which to override the generated name for the image .
as an option, use alternatives, of which there are many .. offhand pThumb, it can help.
