Will you be able to associate keywords to go along with your photo?

Stock photography sites use their own internal search engines; you find an image you’re looking for by putting in descriptive words. Nothing magical about that. It is when you need to convey more then what is physically in an image. You could associate 50 or more keywords with an image. This light bulb is an example of a stock photograph. If this were my photo for sale, some of the keywords I would associate with it are:

• Light bulb
• Glass
• Red
• Clear
• Transparent
• Illuminate
• Idea
• Copy space
