(Help) how to put an image on the pioneer?

how to put a banner in a quest? there is a quest called SCHT spring
and it has a banner in town and I would like to learn doing this help?
what kind of image I should by? bmp?jpg? or other type?
and such and editing also done with the Q.edit?

The image must be a Power VR (PVR) texture file, and only the Dreamcast version can display images. PC will just show a blank white rectangle where the image should be, last I heard. I think it also only works in downloadable quests, because DC saves the images as a separate file on the VMU. The GC version added the ability to compress the image along with the rest of the quest data, so GC can display images in online quests, too. I think you add the PVR file to the quest with the file manager under the Tools menu, but I never bothered messing with it, since it doesn't work on PC.
