That's basically it, I'm looking for a fast and effective way of deleting unused WP generated images from the server and database.
I have found DNUI which looks exactly what I need, but the problem is that it does not seem to be kept up to date or supported very well. And I'm worried that it could screw things up when implemented. As such, if any one knows a good work around, rather than going through and manually deleting these images (which would take a millennia due to the size of the blog), I would love to hear it.
Maybe a mixture of plugins could achieve the same end result or a maybe a certain query could list the ones that need deleting? I am pretty much a novice when it comes to these sort of things so any advice would be appreciated. (p.s. I know that I should have told WP admin not to create these images in the first place)
