I am using the image field to allow users to insert images into the form for preview and print. But because this is for a design group, a lot of the images are saved as PDFs. Is there any way to import those as well and have them show in the fields when opened?
There is if you create a PDF form in Acrobat. You'd use a button to display the image and some JavaScript to prompt the user to select a page from a PDF to use as the button icon. Post again if you like more info.
