Even trivial images should contain source information–what you know or think is obvious others will not. Any reasoning should be briefly included on the image so others can be aware of it. Not all items are as mundane as a grocery list, but any image you create of a personal item should include some provenance and sourcing information.

In some cases there may even be a story to include with the item. And sometimes the most common of images can cause us to remember the best stories.
