Attachment size setting in vBulletin 4

Attachment size of pictures is often a hard decision to take in vBulletin. My personal preference is 500 px width. Here is how it is done:

Admin CP – Settings – Options – Message Attachment Options – Thumbnail Size = 500 – Save.

After you change the settings, you need to do this:

Maintenance -> General Update Tools – Update Counters – Rebuild Attachment Thumbnails.

That’s it.
