In Acrobat Pro, you can edit a button field which allows you to select an image (usually a PDF) for the button. This can't be done in InDesign.
Ask in the Acrobat forums or read Acrobat Help.
Thanks for the quick reply. What I'm trying to do is create a form where someone in our warehouse can insert a photo of a product as well as a photo of the FDA Nutrition Facts panel for each product. The images would most likely be from a cell phone so they wouldn't be .pdfs. Any idea if you think this might work?
That wouldn't work because you can't get a full version of Acrobat on a phone. You would only have access to the mobile version of Adobe Reader. It can be used to fill out forms but not do that kind of creative feature.
Again, you might want to ask in the Acrobat forums.
The photos taken from a phone are probably jpegs, and yes, you can put a jpeg into a button field in Acrobat. Here is a list of all supported formats.
What you can't do is to put the photo from the phone into the button while using Reader on the phone. You need to use the full version of Acrobat to put the phone pictures (jpegs) into the button. And, of course, the phone pictures need to be transferred to the computer first.
InDesign will not be part of the process. Export your form that you are working on to PDF and continue working on it in Acrobat for this part.
Is that what you are trying to do?
YES! That is what we're trying to do. The warehouse workers need to fill the PDF out when products come in and I think they do that on an iPad and/or laptop. Thanks for your help.
I think that's a very ambitious task!
You will need the full version of Acrobat, so no iPad either. But you can absolutely put a jpeg (iPhone format) into a button. Again, this is an Acrobat (PDF) Form issue and not an InDesign issue.
Be sure to test it first, and ask at the Acrobat PDF Forms forum if you have questions as to details.
