I recently downloaded wordpress 3.5.1 and installed it on my website. This should be the website that is launched in the air.
On the demo site when i click on Add Media and want to change the image to thumbnail / medium / large / full screen it works.
Now in the version i launched in the air i can only select full screen and not thumbnail / medium or large.
I only changed my thumbnail at the options-media page for 150 x 150, large to 500 x 398.
Any help ?
