The Image tool allows the user to insert an image into a mobile form in one of two ways:

Use their mobile device's camera to take a new photo and insert it into the form (mobile users only).
Insert an existing image that is stored on their mobile device or desktop/laptop into the form (mobile and web client users).

After the image is inserted, the user can sketch on top of the image using their finger or a stylus (mobile users) or with a mouse (web client), in order to circle/highlight parts of the image, or to create simple notes relevant to the image.

All images are saved in the form as JPEG files.

Note that there is no maximum number of images that can be inserted into a single form. However, we recommend you limit the number of image tools you insert into each form, as forms that surpass 35 MB in size may cause the doForms mobile app to run slowly.

To set how images are scaled, use the image scaling setting under Manage > Mobile app > Settings.
