 * Hi everybody,
 * I hope, someone can help me…
 * I just installed the Nextgen Gallery, but when I upload pictures to Galleries,
   thumbnails don’t show up, neither @ “Manage Galleries” in the WP backend nor 
   on the Blog (if you click, the big pictures do show up). My Webspace is big enough!
   
   I uploaded all pics already organized in Galleries (max. 36 pics per folder) 
   via FTP and I’m using the “Add Gallery” –> “Import Image Folder” functionality
   to integrate into nextgen.
 * thanks a lot in advance!

 * Sometimes, thumbnails don’t get generated due to lack of memory. See if the steps
   in [this thread](http://wordpress.org/support/topic/342099?replies=2) help.

 * Thanks, I tried but it says:
 * ID 99: A failure occurred
 * Anything else I can try?

 * Sounds like image 99 is not valid. Perhaps it got corrupted in the upload. Try
   deleteing it and then re-create the thumbnails. If that works, try uploading 
   99 again.

 * Thanks, but it didn’t work 🙁
 * It says the same thing about all pics/IDs.
    If you click on more it says:
 * “Error 500 – Internal server error
 * Ein interner Fehler ist aufgetreten!
    Bitte versuchen Sie es zu einem späteren
   Zeitpunkt.”
 * which means “internal error, try again later”…
 * It only worked with 2 out of about 20 galleries I tried (thumbs either worked
   for the all pics in the gallery or none)…

 * P.S. re-creating thumbs with pics that already had working thumbs didn’t work
   either, same error message (but the original thumbs are still there…)

 * I’m sorry that didn’t work. It may be aproblem with your host service. My German
   is very rusty, but: Dann kann ich nicht mehr helfen.
