Joomla - Optimising images for use in your website
Optimising images for your website is essential if you want you pages to load faster ... and look better.
Tip: always take a copy of your images before you edit or optimise them. Although most image editors give you the option to save as a new file, it's very easy to forget this and overwrite the original, hence the suggestion.
The following tutorials are provided by About.com and give you a quick simple guide on how to optimise jpeg and gif images.
