Slowly but surely I've been updating the Images on the site to .png format from .gif format. Here is why...
Gif
PNG
The above images were both created from the same original .psp file, However the Gif has to be optimised for the site background colour, As a gif it can only use 256 colours and is dithered as such, this means that the Gradient and quality of the image is less than the png on the right. As for the Background...

PNG
When transferred to a different colour the edges of the transparent gif are jagged because the background colour is set to gray to blend in with the site background, Because this colour will probably change in the future I've started using png's like the right image as they have full transparency, I.e. the Edge is semi transparent so will blend with any background colour and therefore be smooth.
