Pictures?
If you don't know what an oil filter looks like, you shouldn't be changing the oil
The oil filter is under the front right side of the block, it's easiest to access it from the front since it's almost directly behind the belt guards.
You'll have to remove the undertray to get at it though, which isn't difficult at all.
BTW, since you want a picture, here is one:
The oil filter is that pale blue cyclinder visible on the front right side of the engine.
