I need to be able to take photos as part of my jotform, from a mobile phone (both android and iPhone).

I have attached the 'Take photo' widget, but it only allows me to attached a photo that has already been taken on the phone previously.

Is it possible to have a live camera as part of the jotform, like it is on the PC with the webcam when I am editing the form?

 'Take photo' widget will be shown as file upload field on mobile devices. It is not possible to have live camera from 'Take photo' widget on mobile devices. 

However your users can use camera on their phone, take a photo and then upload it to the form using file upload field. 

Hope this will help. Let us know if you need further assistance.
