come out to small unless im looking at the wrong folder. but regardless they aren't as big as everyone elses on here.
You can select the size of your picture using the graphics icon that was mentioned in a previous post. When I use the in-game camera, the pictures are in the Neighborhoods>N***>Story Telling folder. I get a snapshot and a thumbnail, and the latter is much smaller.
You can also enlarge your pictures by using a program like photoshop, gimp, etc.
