What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
If you need something that will allow your respondents to send or upload images, use the File Upload Field.

On the other hand, if you literally want your respondents to take a picture, using their device's camera (whether on mobile or desktop), then this widget might fit your needs - Take Photo Widget.
