1 tip on image optimisation
Web Design - Image Optimisation
Now that Google is looking at download and rendering speeds to rank pages, it’s worth thinking about what you can do to improve your website's rendering speed. SEO now seems to cover every aspect of a web design!
There's a plethora of things you can do to address this issue but the primary and probably the easiest thing you can do is optimise your images. Photoshop has got to be the worst program to use, especially as it always seems to add extra metadata that is totally unnecessary.
One program I have found that does a fantastic job or reducing the file size and remove metadata too is JPEG & PNG Stripper - http://www.steelbytes.com/?mid=30
It's free and fast and all you have to do is drag and drop your images into its window and hay presto it’s done!
You can reduce your image file sizes by 75% by using this neat little program.
One final tip. No matter what program you use to optimise your images, BACK THEM UP FIRST! Just to be on the safe side.
