Important

If the button stops in the middle of your page and not at the bottom increase the number in red at the start of the code, for example in the demo i had to set that number to 500.

left:650px; = How far from the left the button appears you can increase and decrease it to suit your blog.

top:400px; = How far from the top it appears.

You can change the image used for the button by changing the image URL in blue to any image you wish to use.

Step 3. Save your template - You can drag and drop the gadget to the bottom of your design page as position wont effect the gadget.
