Add Image Fields to Documents
Image fields are used to add form fields that enable the submission of images as form data:
Figure 1. Example Image Fields. Empty Field (left), Selected Empty Field (center), Image Added (right).
Please note that image fields are a modified version of the button fields detailed here. The only difference is that the Layout property in the Options tab of the Properties pane is set to Icon Only by default for convenience of use. All properties can be edited using the Properties pane detailed below.
The functionality of PDF-XChange Editor enables a wide range of dynamic customization for image fields. Click the dropdowns below for further information:
1. Click the Form tab, then click Image. A blue rectangle will be displayed at the location of the pointer. This rectangle represents the image field:

The General properties determine the general parameters of image fields:
•Read Only determines whether or not the image field can be edited.

•Orientation determines the orientation of the image field.

•Label Only is the default setting for standard buttons. The text label that the Up Label property specifies is the only element displayed on the button. The Up Label property becomes available in the Options properties when Label Only setting is enabled.
•Icon Only uses the custom image that the Up Icon property specifies to represent the button. The Up Label property becomes available in the Options properties when Icon Only setting is enabled. Image fields are set to Icon Only by default.
•Icon Top, Label Bottom displays a custom image as the upper section of the button and the text label beneath the image.
