# Thumbnails not generated

 * Hi!
 * Since upgrading to 3.5.1 I’m having a really strange issue. I’ve defined the 
   thumbnail sizes in the media section like this:
 * Thumbnail: 200×150
    Medium: 300×300 Large: 0x0 (disabled) Vertical-thumbnail:
   200×335 (user defined)
 * When I upload a big image (ie: 800×1000) all sizes are generated, but if I upload
   a smaller image (ie: 400×500) no thumbnails are generated. I understand that 
   if the image uploaded is smaller than the thumbnail sizes the thumbnails are 
   not generated. The problem is that WP is not generating thumbnails for images
   bigger than the defined sizes (such as the mentioned 400×500 one) either.
 * Any clue about what’s happening?
 * Thanks

 * I’m having a similar issue, not images are being generated after updating.

   EDIT**: Nevermind, my case was definitely a server issue (not debugged yet).

 * Try using a larger image, e.g. 1200 x 800 minimum
