Adding a Media fields to your Form design enables your app users to capture photos, audio or video as part of their Form submission.

Simply drag 'n drop a Media field from the left-hand toolbar onto your Form page, then configure it using the right-hand properties panel.

By default, the Media field will have its Media Type property set to Image.  
This allows the user to capture a photo or select an existing image from their device galley.

Change the Media Type property as desired to capture audio or video instead.

Video capture is generally limited to 30 seconds.  This is to save on upload data bandwidth since videos can be very large - easily 10 times bigger than a photo.

Adding GPS data to your Image

When capturing images, you also have the option to capture the user's GPS location and heading information.
This can be useful for a number of reasons, e.g. if your user is completing a land survey, then you can use their position information to plot each image on a map.

Select the "Include GPS Information" property to enable this functionality on your Media field.

Dynamic Image Watermarking

This feature allows you to apply dynamically generated text as a watermark onto images that are captured or chosen via a Media field during Form entry.

You can define the desired text output via the "Apply Watermark Text" property on your Media field.
The text stamped on the image is driven by a formula of your creation, with options to customise the colour of the text and the position it appears in the image.
And yes multi-line watermarks are supported :)
