Is there a limit to the number of images that can be included in an image picker group?

EDOCBUILDER > eDocBuilder FAQs
The limit to the number of images that can be included in an image picker group is roughly 250 images.  However, from a practical standpoint, if a user can't find the image they want within the first 50 or so images, then they are probably going to give up.  If you have a large number of images, you would probably want to switch to an external asset management system.  Please see this article for more information about using an asset management system.
