In case anyone was interested (despite this likely being a very isolated event): I figured out that my residential lot at 13 Acacia Ave caused the image to show up in Parkside Place and 18 Celebration Way. I didn't use any TOOL on the lot, and didn't enlarge any tree/house looking things, so I'm not sure what caused it, especially since it didn't show up on the map or on 13 Acacia itself. Once I bulldozed 13 Acacia, the image disappeared from the other 2 lots!
It was a downloaded lot from the gallery called 13 Acacia Ave, though I did renovate it a bit with some cc, and I don't know at what point it showed up.
