strange photos on IPhone 5

[Marto298]

Hope someone has an explanation for this. Updated IPhone 5 with the 7 update and sometime during Sunday night 35 photos just appeared onto my Photo Stream. On Sunday I had looked at some photos and all was well and again on Monday morning - only to find that these 35 photos do not belong to me and I have no idea as to the scenery or faces in the pictures. Can someone explain how this could have happened or how I can find out where they came from. A mystery that is a bit scary if someone can magically place their photos onto my phone. Sure, I have I Cloud but no-one knows my user or password.

Someone is taking photos with an iPhone or iPad that is signed in with your iCloud details.

Someone does, time to change your password.

Also, if you have iPhoto and you upload your images they might have GeoTagging that will give you a location of where they were taken.
