Why doesn't the module for uploading pictures to free hostings work?

Question

Perl

Hello gentlemen!
I need help from those who know PERL, because I myself am not strong in it.
The module responsible for uploading images to free image hosting sites (fastpic.ru, imgur.com, trl.lt) has stopped working. It is possible that the API of the services themselves has changed.
Ideally, it would be possible to set the fill at least on trl.lt.
Maybe by looking at the code you could easily determine what the trouble is?
Thanks for any advice.
