==================
Hello everyone,
I'm working on a web-survey where for some questions it is required to take photographs with the camera of the respondent's device (smartphone and tablet) and send them within the same group of questions together with the other answers. The "Upload" question involves too many steps and I'm looking for a customized solution to have total control over the camera.
Thank you
Luciano

Have a look at Offline surveys, they have a question type that allows to take pictures, but I think it works only with their app. But maybe you can get some inspiration.

It must be updated, but you can create a QuestionTheme to allow capture developer.mozilla.org/en-US/docs/Web/HTML/Attributes/capture

Replacing the answer part by an input capture, and updating via JS the system.
