 * Hi,
 * using the nextgen gallery plugin with PHP4 I was able to use the import image
   folder function, which lets you browse through a subfolder of the gallery folder
   in your wp installation.
 * Now that I have switched to PHP5 I cannot browse anymore. The rectangle, which
   has shown the folders previously remains empty. Switching back to PHP4 I can 
   see the folders again.
 * Do you know what might cause this?

 * By the way, I cannot create thumbnails either. Perhaps this is related to the
   bug above.
 * The thumbnail problem occurs in PHP4 and PHP5. CPU goes to 100% and an error 
   occurs, just stating “1”.

 * Maybe you hit the memory limit, check if you can upload small images (resolution,
   not size)

 * Nope, small images don’t work neither. And I have set the memory limit in gd.
   thumbnail.inc to 200M! 🙁

 * What you set with the script and what is allowed from your hoster is different.
   Check with the plugin WP-Memory-Usage your limit, I have no other idea then to
   search in this direction

 * Turns out it was the php.ini memory limit after all. Increasing the memory limit
   in the gd.thumbnail.inc did not work. Unfortunately debugging this was a bit 
   hard, because the function that read the file contents was suppressing all error
   messages and it was not easy to trace it to this point.
    With the increased memory
   limit, creating thumbnails works with PHP4, however PHP5 still shows various 
   problems throughout wordpress, not specific to the gallery.
