Admin tools - intermediate pictures problem!

[freynolds]

I've deleted every intermediate,"normal_", pictures  in an album and it didn't update somthing and now you can't see the pictures when you are browsing displayimage.php...
How can I correct this?

Also each time I try the "Update thumbs and/or resized photos (1)" this error "Premature end of script headers: util.php | (null) " shows up.
