Ok, so I'm trying to use the ImageDataObjectManager or some such to select an image from images already uploaded through the CMS.
Each page in my site can have a different background image and I'd like to enable the site admins to be able to choose the image for the page, the images have been uploaded into a separate dir using file / image upload within the CMS, so now I'd like to extend each page to have one imageID. In the CMS I'd use ImageDataObjectManager to show the images from the background directory and allow the user to select and save the image.
So I've got the ImageDataObjectManager showing, and I can add images, either from the directory, or by uploading, but can't work out how I can disable the add button, and just show images from a directory, and then allow the user to select an image to be the background, any pointers or help appreciated.
