First of all, set up a custom profile field..
Admin CP -> User Profile Fields -> Add New User Profile Field


Create it as a "Single-Selection Menu" type..

Title: Display Featured Photos
Description: By default, we display some featured photos from our gallery on the forum home. If you wish, you may turn these off.
Options: Yes, leave them on
No, turn them off
Set Default: Yes, but No First Blank Option

The rest of the options are up to you, and then click "Save".

Make a note of the field number on the "User Profile Field Manager" (ie. field5).


Now go and edit your FORUMHOME template and find:

$photopostfeature

Replace it with:

<if condition="$bbuserinfo['field5']!='No, turn them off'">$photopostfeature</if>

Replacing field5 with your field number that you made a note of earlier..
