Egg - I do a lot of photo processing by sending photos to my iPhone email account, saving the attached photos, and then emailing the processed photo back. But the one area I could really use this is when saving images processed in Prisma. As we discussed in another thread, this would help identify a filter applied so one could have a visual sample of how a specific filter effects a specific filter. And since I might apply and save a half dozen images, it would be very time consuming to email each one to my email account to identify the filter I used.
