Responsive Images Attachment GUID Selector
In K10 we started with responsive images. Kentico uses Attachment Variants to get this working.
I would like to have a media selector, which returns the attachment GUID. Currently only the attachment URL is selected.
But I need the GUID for almost every attachment helper method in the CMS code.
It would be very cool to have an attachment selector, where the user could upload a new file as cms.file (content) or as document attachment (attachment) but not to the media library.
The selector stores the GUID, so we could get all attachments (with variants) to create our responsive images without any customizations even within Web Parts (like the media selector could do).
