I know I can use this via addons, but prefer to do it manually until the games library will be implemented.

What arttwork is supported for games? How to name it?

Since there is no games library, the only way to display artwork now is using addons.

About artwork naming: the non-written agreement is to name images or trailers or manuals like the ROMs, with different extensions. This agreement is followed by most frontends and downloadable artwork collections.

Addons: if you use IAGL it will use online artwork. In RCB, you can use the scrapers to download artwork or use locally available artwork. If you use AEL or AML, currently you can only use locally available artwork. In AEL the scrapers currently don't work and AML doesn't have scrapers.

Note that in the AEL and AML threads you have links where you can download full artwork collections. As an example, a complete MAME artwork collection is about 50 GB.
