IS THERE A TILESET GUIDE SOMEWHERE?

Because the sprites I made are so large, I have to make some custom tiles to prevent my sprites from overlapping the edges of walls, structures, etc. Is there a guide somewhere that tells which blocks do what?

I've made a template that is 512x256, and I can load it into Ace fine. I have made some test tiles that should work, but there is clearly something missing to get them to auto-fill.

This is what I've got going on right now:



For anyone who cares, here is what is going on:

My sprites are roughly 48x64. This causes their arms to overlap objects. For instance, if a sprite is walking alongside a building, its arm will overlap the building's wall (or roof if it's walking beside the roof tiles).

Normal tiles are 32x32. In order to prevent the overlapping, I have to make special tiles for all edges. They're still 32x32, but there are only graphics on 16x32 of each tile. Everything works out well as far as preventing the overlap; I just don't know how to get the new edges to auto-fill in with the standard tiles. I believe this has something to do with template arrangement (but I may be wrong).

Any help would be greatly appreciated.

EDIT: For clarification, I'm not worried about how to make tiles look pretty, really. I'm more interested in the mechanics of "what goes where" - not the aesthetics.

EDIT #2: If I'm not able to do this directly - if I can't make these special tiles fill in seamlessly with the other tiles - I could utilize parallax mapping to fix this, right? Could I draw in the map as needed in GIMP, and then set transparent (but impassable) tiles on those 16x32 tiles?
