Does a cloud formation really show men riding horses?

An image of what appears to be a cloud formation closely resembling men on horseback is spreading across social media.

The image is spreading around social media attached to various captions (below.) Many claim it was taken recently in US state Florida, while many blogs claim it was taken in either Malaysia or Egypt. Many others have speculated whether this is a sign of the biblical prophecy of the Four Horsemen of the Apocalypse. The image has spread prolifically on social networking websites including Facebook and Twitter.

Look at this picture of the sky ..what it look like to you? A friend took it and sent to me

Horses, chariots and horsemen? Scene from a movie, a Biblical prophesy, just a chancecloud formation?

OMG, look at these images in the sky, These were taken today in Florida. Please share

In reality the image has been digitally manipulated. From the image below you can see the image has actually been cropped and was used in an advert for a Kenwood multimedia system for cars.

This is where the image came from.

Thus any claim that this is a genuine photo or a sign of any biblical revelation is simply untrue.
