Not a Bug Image Height/Width

Its working fine for me. I've got mine set at 800 and 600 and it shows width 800 and height 600.

Could be that you have another user group that you are in that has 1,920 set as height and is taking the larger value (which is how 'allow' works with permissions).

I marked this as a Design Issue, as the only way I could reproduce it was to put myself into 2 user groups, make one user group settings 800x600 and the other one 800x800. being the xenforo permissions for 'allow" takes the higher setting, it displays 800x800. If I set both to 800x600, it then displays 800x600.

Could you check and make sure you don't have another group permission set to 1,920 by chance?

 

it wouldn't work correctly for anyone if it was a simply matter of using the same variable (which its not). The only way I could reproduce was making another user group have a larger value.

Since I can't reproduce locally or even here on the demo, I'd need full access to your site to further troubleshoot.
