Text RPG Creator: Insert Monster Image

I've been noticing a trend to link to external images, something not favored here for various reasons (Broken links, extra moderation, copyright, etc). It made me think about a once suggested option to have a library of monster images that can be inserted into a Post. Admittedly, I had something similar in my own World of Medieval and FE, however the art was my own creation and thus localized. Having it site wide was not followed up on much simply because the focus is Text Role-play Gaming where things should be described rather than having a visual at every turn, however I am placing this here for Discussion because there may be a need and of course it will be a highlight of Role-playing here.

The proposal is a Dungeon Master / GM will have a list of royalty free monsters / NPC images to choose from an in-house database. Once selected the image(s) automatically appear within the Dungeon Masters / Game Masters Post.
