Layerstyle maps with nice pattern fill textures are a great way to make maps quickly in photoshop with the added bonus that if you want to extend the map off one edge, you can just increase the canvas size and keep drawing (and crop afterwards to make a new map if you want to). If you're after objects, then I suggest you either look at the Dunjinni website or in the 'news' section of this site (look for Mark Olivia's symbol sets), where you will find lots of pngs of objects like Barrels, armour, statues etc to put in your dungeons.

Welcome to the Guild! You have some nice clean battlemaps there!
