I dunno about pictures (It's true, that anyone with a basic knowledge of photography can fake a picture of a miracle. I did see a video once of a priest excorcise a woman, it was very highly disturbing. The lampadi in the church shook, and the woman was shreiking, an inhuman sound if I ever heard one. It was highly disturbing.
Anyway, I did hear of one miracle that could not be explained by anything medical.
A few years ago, a church was being restored in Russia my parents visited right after, so it was still fresh news & people were talking about it pretty much non-stop. One agnostic construction worker was sent up to gild the cross on the highest dome. He fell, bouncing off the roof and then to the ground. The church was the biggest in the city, and was many stories high. While falling he screamed "Gospodi Pomiluy!" When he landed, he had not a bruise on him, nor any broken bones. He walked away from it, and was baptised the very next day. That's pretty darn miraculous if you ask me. And yes, before anyone asks, it was an MP church.
