Ok, I'm relatively new to Acrobat, and I heard this might be possible. I'm trying to create some sort of store or database of images that's saved to the PDF itself, so when someone opens it in reader they can choose from various images and place them within the doc.
Is this at all possible?
EDIT: I see you can have file attachments, is there a way to be able to insert an image file attachment directly into the PDF in reader? All it seems like you're able to do is strictly open it or save it.
The ideal way would to use document-level icons, but there's a silly bug that causes them to get wiped out when you perform a Save As operation, which completely defeats the purpose of having them at all.
The workaround is to set up a series of buttons, normally hidden, to contain the graphics/images/text that you want. I usually keep them on a hidden template page. The icons can be retrieved using the buttonGetIcon JavaScript field method and used to populate a visible button using the buttonSetIcon method. So, the images are stored in the document as button icons of hidden buttons. Set the button layout property to something other than "Label Only" and you should see where you choose an icon source from a file.
To populate the hidden button with the images, you can either create the buttons manually and select the images manually, or you can set up a batch sequence or code somewhere else (e.g., custom toolbar button, JavaScript console) that creates the buttons and sets the icons. It's probably best to do a few manually at first so you can test it out.
