Rework note and example in definition of "image of text"

The note is confusing (see #5012), as it appears to exclude important text in combination with other visual elements within the same image, which is not the case.
The example is confusing because the context here is unclear - if the main important aspect of the photograph is to show the portrait of a person, and they happen to wear a nametag...then that nametag may well be incidental...unless the whole point of the photo was to in fact show/illustrate the person's name by including the nametag? In any case, this example - particularly coming after that note currently, adds to the confusion.

If the note was intended to set up the idea of text being incidental, this should be reworded. And if the example was in reference to the *note*, it should be part of the note.
