 * Hello,
 * I want to stop WordPress from creating images in lower image sizes. Allthough
   I tried to set all parameters in Admin panel -> Settings -> media to 0, my ftp
   server shows me, that wordpress generated the files.
 * How can I disable the automatic image resize function?

 * WordPress will not delete any media sizes that it had already created when you
   set your Max width and height sizes all to zero.
 * If different sizes are still being created when you add media, it is most likely
   being done by a plugin.

 * Image sizes and thumbnails are also created by themes. Check your theme’s functions.
   php file for the thumbnail sizes created.
