I would guess that the picture was not properly secured if a picture fell off the wall.
The force that holds a picture on a wall is the force of friction between the back of the picture frame and the wall. This friction prevents the picture from sliding or falling off the wall.
A picture falling off the wall can symbolize a disruption in stability or harmony in one's life or environment. It may represent unresolved emotions or conflicts that are coming to the surface. In some contexts, it can also be seen as a sign or message, prompting reflection on the significance of what the picture represents. Ultimately, its meaning can vary depending on personal interpretation and the surrounding circumstances.

In some cultures, it is believed that a clock falling off the wall is an omen of bad luck or impending death. This superstition likely stems from the association of time with mortality and the idea that a falling clock signifies the end of someone's time.
Not all naturally occurring phenomenon can or should be interpreted as a sign or omen. Unless the picture was of someone specific and of significance to you personally I would not take it too seriously. That said there is a superstition that says a picture falling from the wall, for no apparent reason is the omen of an imminent death, however, the glass in the picture must shatter for the omen to be believed as true.
Not all naturally occurring phenomenon can or should be interpreted as signs or omens. That said, a weddingphoto falling from the wall, when no mundane explanation can be found, could be read as meaning the marriage is in for a rough spell, particularly if the glass breaks.
