AJAX image uploads now available for forum posts

Written by Richard Heyes, RGraph author, on 6th May 2022

It seems to be quite the rage at the moment - ajax file uploads for forms. So now you can attach up to three images (each of which can be up to 100k in size) to your forum posts (not replies though). If it gets abused I'll have to review it's use - but I think it should be fine. Famous last words... I've also implemented deep anchors - so instead of just linking to the page and then having to find the reply that may interest you - you can link directly to it. See it in action on the forum:
