Nice, snippet! One would of thought this functionality would of been built into WP_Customize_Image_Control, then again, extending the class WP_Customize_Image_Control isn't that much code anyway.

Just curious, @eduardozulian the comments found here do not seem correct. Since if the $my_context_uploads is empty the method just returns.

@zanematthew, you're right. I did some test months ago and I kept getting all my attachments, but I don't think that's the expected pattern. Thanks!

Just updated the code with some examples too.

Okay, back into extending the WordPress theme customizer extensions. I'm still using this snippet for uploading textures, backgrounds, and logos. I'm not sure if something changed, but I can' seem to remove the images after they are uploaded. However, I noticed the WordPress added some features to the Live Theme Customizer particularly for Header Images. I see new buttons for "Hide Image" "Randomize Suggested Images", and they also cued in the newer Media Uploader for the header images in the theme customizer.

My memory may be failing me, but I thought we could remove the images that were uploaded to our custom contexts? Or, maybe I have a little bad code where it's not showing up anymore? Just can't seem to remove the images that I've uploaded.

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?
