You have, no doubt, heard this before:

“A picture is worth a thousand words.”


What did you see in that image ?

(The previous image was created using a program called “Textorizer” – it allows a background image to be overlaid with text)


An image is a two-dimensional representation that has a similar appearance to some subject—usually a physical object or a person.

In a literal-definitional sense, an image can be...

• a map• a photograph• a drawing or painting• a screen display

As we see, an image is a two-dimensional representation.

* The 3-D shapes in the previous image are still 2 dimensional – it is just that our brain “sees” them as having depth, length and width.


An image can not only be visual – it can also be mental.

When we view (or recollect) a place or event or thing, we form a mental image of it.


If you think of images as mental, then you have to consider that the viewer can influence his/her interpretation of the subject of the image.


Recollection of past events, places and things can be influenced by new information, thus possibly “altering” the image.


Think of how written or verbal information, instructions and knowledge are created.


Now think of how easily information, instructions and knowledge can be misinterpreted – because of the viewer/receiver’s context, history and perspective.


Often images are used by themselves to convey information.

Of course, both the creator and viewer have to have a common understanding of the meaning.

Does a picture (image) have any connection or relevance to a fixed number of words ?

Does a picture (image) have to have any connection or relevance to any words ?


When using images for educational purposes, we need to be aware of how meaningful an image can be, or not.
