WPFORO Advanced Attachment Addon - Media Library
This is already in our to-do list. We'll add it in future releases for sure. But I'm sorry I have no ETA at the moment.
Thanks, we'll wait for the update before migrating to the new forums as getting images into media is crucial. We run a large forums and people are constantly uploading images. Due to this if we migrated to wpforo now people would upload their images and then the attachment addon will get updated in the future which would leave all uploaded images prior to update not included in the media.
We'll be looking for the update!
WordPress Media Lib is very heavy for forum attachments. It saves lots of data in wp_posts and wp_postmeta table for each file, also it generates many copies of uploaded image with different sizes, which is not needed for forum. We decided to create separate Attachment Management system with admin page. This will keep forum attachments intact and it'll not make WP system heavy.
Currently we work on this and hope to add it by end of this month.
