P - The purpose of the photograph was for Lai Afong to earn money.

I - The general public of the US.

P - The point of view is the US. The US is an outsider in this conflict, so this image must have been what a third party would have thought of this incident. It’s somewhat unbiased, but also inaccurate because the artist most likely never saw this scene.
The photo also shows Britain and China in black and white. From the American perspective, this simply illustrates the superiority of the relationship.

P - The purpose of the photo is to inform people of the events of the Opium War, but also to slander Britain for its humanitarian actions.

P - US artist, because it is from the US newspaper. The drawing reveals more western style art. John Bull, who is a personification of Britain, is also included in the drawing. In this picture, Britain is forcing them to have opium which also depicts that Britain is more superior than China. 
P - The purpose may have been to point out wrong doing of Britain during the opium war and racism at that time.

I - This is aimed toward the general audience, or a group photo requested by these people in the pictures.

P - No particular point of view; may show how the opium culture developed in china

P - To take a group photo; maybe show their punk

I - This is for the Chinese public who consume Afong's media. 
P - Lai Afong was a very successful Chinese photographer. There is not specific bias that the photographer had that influenced what the photo portrays. However, it is worth noting that the photo seems to portray men in the upper class smoking the opium. The photograph is portraying a group of friends loitering around and utilizing the illegal narcotic. The photo looks posed and everything in it seems purposefully placed.
P - There may be multiple purposes to this photo. On one hand, it may portray the lack of enforcement of the law against opium in China, which suggests that there was instability in the Chinese political system. On the other hand, it may just show the luxury of these people, and may show the lower class that you can become rich and smoke opium like these men.

I - General Chinese public (because Lai Afong generally catered to the public's needs since he was after monetary gain and informed his audience of a certain topic.)

P - This artwork was created by Lai Afong (1880). Lai Afong was one of the biggest and most influential Chinese photographers of the 19th century. 

P - The purpose of this picture is to depict the general Chinese societal image at the time. (influence of opium illegally exported by the British)

I  - The intended audience of this photograph could be the Chinese government officials, or the general public itself. 

P - The photographer was a famous Chinese person named Lai Afong. He created the Afong Studios. He is photographing his friends smoking opium. The photographer is showing how they lived through the Opium Wars and after. It seems likely that the photographer was trying to portray upper-Chinese classmen smuggling in opium and eventually, smoking it.

P- The photo portrays a few Chinese men smoking opium years after the war. The intended audience of this photograph was established to be Chinese people in general, so it seems likely that Lai Afong took this photo to warn the Chinese about their addiction to opium. This is because the photo was taken in 1880, years after the opium war came to a close, even when opium was illegal, which goes to show the seriousness of the addiction. 

I - The intended audience of this cartoon is the people in the US, who would have the most exposure to the US newspaper. 

P - The person who drew this cartoon is unknown however, it most likely originated in the US. The point of view of this cartoon is the US. This cartoon is most likely a third-party incident as it seems the Chinese lived there. The cartoon seems highly inaccurate as it is made by a person who physically did not see this incident. From the American perspective, this shows a sense of superiority by forcefully trading opium. 

P - The cartoon features English, such as “John Bull’s Merchant,” so we know that this cartoon was to inform the US general public. Additionally, the caption for this cartoon said it was published in a US newspaper, which reinforces the previous claim. Lastly, this cartoon seems to have less bias, because it portrays the Chinese and British under a negative light, which further strengthens the claim that this cartoon WAS intended to inform the general public of the US.
