If your image file is greater than 250kb you will need to use a piece of software to optimize the image. I use Adobe Photoshop, this is an expensive piece of software and something that I would not recommend you buy (unless you do a lot of PC graphic work).
I also use a FREE piece of software called Paint.net . You can download a free copy from this link:

Once you have downloaded & installed Paint.net click on the link below where you will be able to watch a web-cast video that Jonathan, our IT man, has produced to help you.
