Link Buttons
Please save buttons to your own server (right click, save as). Link the button back to http://whoa-cool.net/gachapon/ - if you're not familiar with HTML you can copy this code:
<a href="http://whoa-cool.net/gachapon/" target="_blank"><img src="http://YOUR_URL/imagename.gif" border="0" alt="Gachapon Fan" /></a>
