I don't feel I lack imagination but others may beg to differ . I was however noting the warning
and since I don't have access to the code for the button itself I was not sure how easily it could be changed nor how the data fields would respond to a different graphic.If you change the code, it might not work
I also prefer to maintain the look and feel of my site and the existing button doesn't sit well with that.
If you want visitors to vote by clicking on the button, then a button in the footer will not be seen by visitors to many sites where the footer may not be visible without further scrolling of the page(s).
I will do some experimenting with the button graphic. In the meantime I have just resized it.
All I would put on the button is;
Cumulus topsites
Rank with the sunburst graphic
and
something to indicate that clicking the graphic will actually to something - i.e. vote - which is missing from the present graphic.
