Perhaps you are not entirely sure whether the story accompanying the photo or video is accurate.
Ask yourself 3 questions:

1. When did the images first appear? Is the image older than the event it is now being used to refer to?
2.  In what context did it previously appear? Was this photo perhaps used three years ago in connection with a similar disaster in another country?
3. Was the image taken at the stated location? Small details can reveal a lot about where, when and in what context an image was made. Pay attention to:
   • Location: street names, number plates, shops, road signs, buildings – do these match the claimed location?
   • Language: which language do you see or hear on signs, in shops or spoken by people?
   • People: do ethnicity, clothing and context fit the supposed location?
   • Weather: is it sunny or cloudy? Snow or summer conditions? Does this fit the date and location?

Don’t rely on a single post, a single website or a single image. Check whether multiple reliable sources present the same story:

• Is the image also being shared by other (news) media or trustworthy organisations?
• Do they describe the same event, location and timing?
• Are there differences in how the image is interpreted or framed?

Tip: with a reverse image search you can check online where the image has appeared before and in what context. This allows you to quickly see whether the image has ever been used for something else.
