Firstly, amazing script... fantastic work. Made the image transfer and post modifications a mostly painless process.

Although, I did have a couple of issues with the script... it was "hard crashing" on
one post that had some "interesting" text in it. It didn't like all the URL text at all

So, I simply made a backup of the original post text, then removed all the url text, restarted the script and, once it finished, edited back in the original text.
Additionally, there were 2 or 3 other posts that ended up returning a "(403) Forbidden" when the script attempted the POST to edit the image URLs:

The posts in question definitely weren't in locked threads etc, as I was able to manually upload the images to TalkImg and then manually edit the image URLs into the posts, so I'm not sure what happened with those.
Thankfully it was only 2 or 3 posts out of my 10000+ posts

over 514 pages that the script had to check and only about 3 or 4 pics in total, so it wasn't really a big deal.

Again, great work on the script... and a huge shout out to joker_josue for setting up TalkImg.
