Hi @Robert

1. I have put this code in my theme functions.php to be able to embed images. The code works well because it embeds the images maximising the size in posts.
2. The problem is that you can only attach 1 image per post, which is why today I have purchased Advanced Attachments, together with a bunch of other wpForo premium add-ons.
3. I am testing the features and I realized that once Advanced Attachments is activated, it appears that I lose the ability to embed images in posts (see point 1)

I am going to attach a couple of screenshots in the next posts with to illustrate the problem.

Thanks
