Documentation is the act or an instance of the supplying of documents or supporting references or records. Supporting references may be in the form of written information, media, and other content used. This also referred as the process of providing evidences.
In biography writing, evidences or supporting documents serves as ‘eye candy’ for the readers as it concretize the point that the writing wants to emphasize.
Graphical insertions like photos are like ads that trap the readers in a glancing moment. If a photo is interesting enough, the reader will stop to it and read the caption and if the interest stays there the title of the article is read next. If the beginning of the article is catching enough, the reader will read all of it. In conclusion only 5% of readers read an article but almost all the photos get noticed. There are times that pictures can do more to tell a story than words.
Photographs allow readers to see exactly what a person, place or event looked like out without having to infer from just a word description. A picture also often times packs much more of an emotional punch than a paragraph and can do more to engage and interest readers.
In general perspective, pictures are up for interpretations and allow readers to make their own judgments on what they see.
