# Thumbnails not renamed

 * I can’t say if this is on all files but it seems so, when I rename a file very
   often the WP generated thumbnails are not renamed. I saw this was an issue in
   the past, so I’m surprised it is happening with the current version.
 * I’m running LocalWP, though that should not matter. The site has the following
   plugins:
   Classic EditorDuplicate PageEnable Media Replace (deactivated)Envato
   MarketGoodlayers CoreGoodlayers Portfolio Post TypeLocation WeatherNinja FormsPhoenix
   Media RenameSite Kit by GoogleSlider Revolution
 * Thanks!

 * Hi [@carnelianwoods](https://wordpress.org/support/users/carnelianwoods/),
   I 
   never had this kind of issue except for unregistered thumbnail dimensions: in
   this case Phoenix Media Rename is not notified about the existence of the files,
   so it can’t rename them.
 * I can’t try Goodlayers theme because they don’t have a free version, but I will
   check Enable Media Replace to see if this can cause this kind of issue.
 * Thank you for reporting!
   C.

 * I’m new to WordPress but happy to help debug this. How do I determine what sizes
   are registered?
 * If it helps, looking at the media files, for example one file I renamed had these
   sizes both before and after the rename:
   150×150, 300×200, 300×368, 600×346, 600
   ×366, 600×389, 768×513, 1024×684, 1280×700, 1536×1025

 * You can see the registered sizes in the Media section of your site Settings (
   <your domain>/wp-admin/options-media.php).
 * Usually the registered sizes are square (themes and plugin can add sizes other
   than WordPress defaults) and non square images will generate sizes that have 
   the maximum dimension limited by registered sizes, as an example: if your site
   have 300×300 and 600×600 size registered and you upload a 1024×512 image (2:1
   proportions) you will obtain 300×150 and 600×300 thumbnail, other than your original
   image.
 * Hope this helms 🙂

 * That page contains only code to ask for max width and height for:
   thumbnails,
   currently 150×150medium, currently 300×300large, currently 1024×1024Which looks
   like the WP defaults page.Are the other sizes I’m seeing then “not registered”,
   or do they come in someplace else?
