Place tiny photos or graphics into the text between paragraphs as near to the place where they are first stated as feasible, but not before. Larger graphics (for example, elaborate scatterplot graphs) may need to be presented individually on the next full page, correctly oriented. In general, try to avoid having more than one image on a page at once; if this is unavoidable, make sure that the page breaks within the page number of the document occur at places where such images can be comfortably placed. Photos and other illustrations can add much to your writing by helping to explain complex concepts or procedures. For example, a photo of the inside of an atom helps readers understand why physicists study atoms. Photos also can help make your writing more interesting. For example, a photo of a valley with tall trees in it makes a scene from nature seem more dramatic than just reading about it. As long as you use caution not to go over-the-top with your photo choices (for example, including every single fascinating thing you can think of for your reader to look at!), photos are a great tool for writers to enhance their projects. There are two main types of photographs used in essays: those that stand alone and those that support the writer's argument. A photograph that stands alone can be anything from a simple picture to an illustration. It should give the reader insight into what is being discussed in the essay without taking up too much space.
