Image formats
File names for images
Acceptable web ready image formats are jpegs, GIFs, PNGs, at 72 DPI (dots per inch).
Give image files meaningful names; avoid jargon files names for example ‘img123.jpg’.
This allows fast download whilst keeping image size to a minimum for the web.
Alt text
Provide a short clear, contextual and meaningful description of the image. This is a very user friendly format for people who are screen readers and will make the content accessible.
If an image is not essential to understanding the content, use empty quote marks: "" as the alt text. For example, a decorative image, this may include logo image.
