Image filename

An image filename is a unique name used to identify an image in a file system. It consists of a name we assign to it ourselves and a file format.

The filename is your chance of explaining the image content to the crawlers. It should:

• Be readable to humans (don’t name your image IMG_025.jpg)
• Be as descriptive as possible
• But try and keep it short – don’t use stop words like a, the, it, to etc
• Be somewhat unique (using names like shoe1.jpg, shoe2.jpg, shoe3.jpg will not help you much)
• Include keywords
• Use hyphens (dash) instead of underscores
