Visual Arguments

It is said that a picture is worth a thousand words. I believe this to be true. When I see a picture, I immediately start to make observations about it. I notice the obvious things and as I look at it longer and closer, I begin to notice the slightest details. If I was given a picture to look at and discuss with someone else, I would be able to hold a conversation for a decent amount of time. There are many observations and inferences to be made; as well as many questions to be asked. However, don't think that images can suffice when compared to the impact of words sometimes. Yes, images may be able to give you a better view of an actual event but images can't tell the viewer exactly what was happening and why. They can't tell the viewer exactly how the people involved in an event felt. The viewer can infer and come up with possibilities in their mind but they can't exactly pinpoint someones emotions and thoughts; whereas they could be well informed through text.
Although, I don't believe that images are always sufficient in making an argument, it is true that visual arguments are possible and sometimes even more powerful. What comes to mind when I think of visual arguments is how political and social issues are brought to light through images. Sometimes the public can't see everything for themselves so an insider may be able to take pictures and share them, informing the public of cruelties and harsh realities that they would have never believed or understood through word of mouth. Visual images are more effective in arguments when they provide solid documentation that any skeptic can see with their own eyes.
