Indexhibit Support

Hi there,
I'd like to integrate a paypal button on my website like that: http://www.maxf.eu/zines/graisse-animale but everytime I try customised buttons, there are weird spaces between the buttons...

I don't know how to fix that :(

Obviously not an indexhibit problem per se.
I would try searching the web with keywords like "customize paypal button"
And of course the use of css - check the second red link in the Useful threads post. Some links there will give you a headstart.
