I also need to accomplish that, and tried with this solution Turn image upload into image url column but it doesn’t work very well when there is multiple images, because the data is often sent to the other doc table before the _Deref_Object has finished generating the image paths, so not all images are sent on the first attempt.
I tried adding a delay, but since it’s an approximative delay, it’s not very reliable. I also tried with a second button to refresh the image paths before sending the data, but it can get confusing for the end user.
I also don’t like very much to use non official formulas, but it’s the only way I found yet.
Any ideas how to send the image paths via crossdocs, and preferably using documented formulas?
