To use your own image click on the Browse... button and in the new window find the image you want to use. Click it and click on Open. Now click the Use my image button.
Hint: We use images that are 500px high and 444px wide so try and use this as your image size. Don’t worry if any of this is a problem, when you use your own image we resize it for you.
Please note, files over 2Mb will not work. If in doubt, try it, if it's too big we'll tell you.
