Ok so first I did check the PHPBBs FAQ section before writing this post, but it suggests to contact the admin. I'm able to upload attachments without any problem, but is there a limit to the number of attachments I can have per post? I cant seem to add or display more than 2.

You should be able to add more than 2 images. Try editing your msg afterwards, see if it will let you add more then

Hi Lee, I'll give it another try. I did make a post in the Anorak Corner section on the "Your 2020 Builds!" thread and you should be able to see what happened.

The error I'm getting:
The attachment 20210227_135539.jpg is no longer available

The Thread:
viewtopic.php?f=11&p=32503#p32503

It's possible just me doing something wrong. Shame there's no test area on this forum.
