Regular members? As in the specific usergroup "registered" ?
Assuming your registered group ID is #2, in the template "album_display", find:
HTML Code:
<select name="type">
<option value="1"<if condition="$type == 'image'"> selected="selected"</if>>Pictures</option>
<option value="2"<if condition="$type == 'sig'"> selected="selected"</if>>Signatures</option>
</select>
Replace it with:
HTML Code:
<select name="type">
<option value="1"<if condition="$type == 'image'"> selected="selected"</if>>Pictures</option>
<if condition="$bbuserinfo['usergroupid'] != 2">
<option value="2"<if condition="$type == 'sig'"> selected="selected"</if>>Signatures</option>
</if>
</select>
They'll still be able to access signatures if they know the code, so in the album.php, find:
PHP Code:
$type = $_REQUEST['type'] ? $_REQUEST['type'] : 1;
Replace it with:
PHP Code:
$type = $_REQUEST['type'] && $bbuserinfo['usergroupid'] != 2 ? $_REQUEST['type'] : 1;
