Will it do the same in CMS articles? If not, what would it take to add that functionality?

I read in the thread that the CMS is not supported. The post was dated 2012, so don't take my word on it. :)

It's not supported. It would take quite some efford to read the articles the same way as it does for the forum posts and apply the changes. Essentially it needs another cronjob with almost no shared code.

It is very useful product and I've used it for years
I will soon be ready for vb 5
Do you plan to do this?

I haven't tried it yet, but it may work probably just out of the box or with very few changes in vbulletin 5.

I am very much looking forward to hearing good news
This is one of the most popular products that are offered by you

Sorry for my bad English

One thing I can confirm is that it works in v3.8.7-P4 without any changes.

For what I need it, I've done a small modification, mainly do a backup of the post before updating it.

What I'm most struggling with is the 27000+ posts that have images in them. It is slow. So I'm now rewriting parts of this addon so that it can run from cli.

If there is interest, I can contribute or publish the final cli version once it is finished. The code will not be nice though, I haven't coded much php in the last couple of years.

working great :) but if the thread is deleted does it clean up the un-used images?

No it doesn't clean un-used images :( can't use this sadly if it can't do it.

On large forums you can't tell if an image is reused. This is a plugin for typically very large forums, where the lack of images is much more critical than a few too many. Also, it may come handy to have a copy. Please think about it as a feature :)
