XThread Images

[Flabaliki]

So I have a download forum, similar to Leefish's, in that it hosts Sims content with plenty of pictures and such.

Now I only found out about XThreads long after I'd already had my site running, so even just adding the fundamental elements that my forum needed via XThreads was a long process. All that worked out great, and the forum has never been better

Now what I'm wanting to do for the next version of my site is to allow multiple uploads of images and files, rather than the one by one of the default MyBB system. I currently use an XThreads field for forum display pictures, which is brilliant. The problem being that, all the pictures of current uploads are done via the MyBB attachments system, and I was wondering if there would be a quicker way of converting them over to xthreads.

I tried to do a htaccess url rewrite to make the extensions .jpg and then use the URL option for the fields, but that just spat out an error. If there is any possible quick way, that'd be awesome. If not, it's not -that- big of an issue, because I can just leave those pictures with the old MyBB way and just force new uploads to use XThreads.

Thanks for any help provided
