When you embed the image in the form, a copy of the image information is stored in the form. If the image field will be used to load images dynamically when the form is rendered, do not select the Embed Image Data option.
Note: If you are using the paper forms barcode object, you should not select the Embed Image Data option unless you have assigned a collection, that does not include image fields, to the barcode. The embedded image data is larger than the paper forms barcode object can hold.
