Some photos are being resized to thumbnail in ODK Collect prior to/during submission

Hi @John_Ellis! This isn't a server problem. My guess is that the user took the picture with the camera, then instead of using that picture, they used the Choose button to choose the picture (or used another camera app) and somehow chose the thumbnail. I'd start trying to replicate that.

Finally, when you get a chance, please introduce yourself here. I ask because not many people are using Mesas, so you must have a pretty cool project...
