I'm creating a new Forms process for uploading receipt images people take with their phones. The photo quality is often too poor to convert to black and white. As is, even on a slow month I'm expecting 10K full color images from phones/tablets. These are not computer literate people, and there's over a thousand of them, so I need something that doesn't rely on them editing the images themselves.

I've done some experiments using ImageMagick to convert volume image files, but it did not work, I may be asked to encrypt all volume folders at some point, and I've had terrible experiences with people messing with volumes. 

I'm going to move the customer to 12, and I don't know all the new features, so I may be overlooking something.

A project I worked on saved Forms Uploads to a drive and thoroughly scrubbed for viruses before being saved to the repository, but it required a LOT of custom programming. It was done in 10.4 before save to disk was a feature. 

Is it possible to have Forms 12 uploads save to disk, and then delay sending those images to the repository until a tool like ImageMagick can convert the images to grayscale? 

FEATURE REQUEST: Please allow us to do grayscale conversions with either QF or Workflow or best of all Forms Save to Repository.
