The preview in the admin panel does not work, why and how to fix it ???

Question

MODX

Hello!
A question about multiTV
How can I make it so that when uploading a photo to the admin panel, you can see the photo itself
, otherwise, it turns out that I uploaded pictures to the admin panel, but I can see them only by their name ...
version Evolution 1.4.0
Method as before , no longer valid for previews?
In the multitv.js file We
wrote the path assets / tvs / multitv / js
and in line number 226 we changed “thumbPath[0] = '/assets/.thumbs';” on -> "thumbPath[0] = '/assets/'
I just see that everything is different in the multitv.js file.
What is another way???
Thanks in advance!!!
