The image itself is a fully-formed Imagick-generated PNG file, and can be downloaded directly from the controller. However, I'd like to allow the user to save it to the site to access later, and I'd ideally like to leverage the attachment system and all the various benefits it offers me over saving the image manually.
Has anyone tried to use the attachment system this way? Is it feasible, and if so, where would you recommend I start?
As always, thank you for your time.
