You have the option to place text or date/time overlays on photos taken with both the single and the multi-photo fields.
To add an overlay, click on your desired photo field and then click the "photo overlay" button in the settings panel on the right.
Next, enter the fieldkey of your text field that you wish to use as the overlay.
In the example below "alpha_1" is the basic text field we will be using as the overlay.
Let's also ad a date/time stamp on the photo
To do this, simply click to highlight that option in the settings window.
On the app, be sure to enter your caption BEFORE taking your photo. If you enter the text after the overlay will not display on your photos.
