I want to give my app the ability to let the user upload a image from their photos (camera roll,gallery,etc). Is this possible in Codea?

You’d need an add-on, there was on written a while back which can be found at:

I don’t know if it can be used for uploading to an app, I’ve used it in my Celtic Knots app for saving images to the camera roll.
