Edit Attachment Size But No Change


Active member
Maybe I'm not going it right? I changed it, then went to a post and click on thumbnails but it seems to be the same size. I went back and edit the post again and then simply click ok to attach to post and still not change. Do I need to rebuild it or delete and upload again?

I'm not terribly familiar with that part of the admincp at the moment, but when in doubt, Control F5 for a hard refresh.

And of course changes may not be retroactive i.e. new attachments may reflect the changes you made.

Are you talking about this setting?

Admin CP -> Home -> Options -> Attachments -> Attachment Thumbnail Dimensions

I don't see any option to rebuild attachment thumbnails in the current beta. The only way I see to generate a new thumbnail is to upload the image again.
