Oops, discard that last comment. It reappeared. :) Love this snippet!!!

@nativeimaging @eduardozulian seems since 3.9 was released a few things changed, mainly a bug arose, the "remove" option is now gone. Looking into a fix.

hello,

i trying out your class and it act strange.

Right after i

require 'My_Customize_Image_Control.php';

and i save the new image options i get an error

Fatal error: Class 'WP_Customize_Image_Control' not found

And the Website is not loaded.

So after outcommenting
//require 'My_Customize_Image_Control.php';

the website loads correctly again.

What do i need to do to fix this?

Regards

AHHHH!!! THIS IS AMAZING!

@wesweat You need to go into your functions.php and add it from there. Look at https://gist.github.com/eduardozulian/4739075/#comment-823136

Anyway, I'm writing to ask how to actually use this? I'm not sure what to put inside the context. Anything I put in doesn't seem to work. The Uploaded tab is still hidden.

cool and time saved

@eduardozulian thanks for this! Wicked to extend this capability. Any resources that might point out how to implement or grab the new CustomLogo in the header.php?
