Fix for Blank User Defined fields being Displayed

[gtroll]

I am using the user defined field and config is set to "Picture information are visible by default" and when the field is blank coppermine will display the field name with no value.
This code will make it so only fields with a value are displayed.
Line 231 displayimage.php
Replace

Code Select Expand


for ($i =1; $i<= 4; $i++){
      if ($CONFIG['user_field'.$i.'_name']) {
            $info[$CONFIG['user_field'.$i.'_name']] = make_clickable($CURRENT_PIC_DATA['user'.$i]);
      }
   }

With

Code Select Expand


for ($i =1; $i<= 4; $i++){
      if ($CONFIG['user_field'.$i.'_name']) {
          if($CURRENT_PIC_DATA['user'.$i] != ""){
            $info[$CONFIG['user_field'.$i.'_name']] = make_clickable($CURRENT_PIC_DATA['user'.$i]);
         }
      }
   }

This will probably work with other versions of coppermine but it hasn't been tested....
