full size image

I’m having the same problem… The Admin only lets you define the thumbnail size and medium size but there is no sign of full size settings.

If anybody is looking for thumbnail and medium size, go to:
Settings>Miscellaneous>Image Size

Anybody know where to find full size?

The full size is just whatever size you upload the file at and therefore there is no setting.

When inserting into post make sure you click the rado button that says full size.

Here is the solution:

Turns out WordPress rescales the image with html. To change it you need to edit
wp-includes/media.php

On line 34 look for $max_width = 500; and change the 500 to whatever you’d like.

Save and your done ??

You can also edit your theme’s functions.php file. Doing it that way means your fix will survive an upgrade.

Add this to functions.php:

$content_width = 900;

replacing the 900 with whatever width you want to use.

I discovered this on this site and it worked on mine.
