Salefroce Help's response that put me onto you:

Thank you for contacting Salesforce support. I tried to link your image for you hoping it was something simple I could fix. Unfortunately it is the link to the URL. So what you will need to do is log onto this website http://community.salesforce.com/sforce?category.id=developers tell them the application you have installed and they should be able to provide you with the proper URL for this button. Once you have the URL you will go to Setup/App Set Up/Accounts/Buttons and Links/Under custom buttons and links please choose upload a picture/edit / then put the proper URL in this box. I wish I could help you further unfortunately we do not support this app. If there are no more questions I will close the case. Just follow the steps above to fix once you get the proper URL.
