Hi I have 2 issues with the new version of sigpro and I would appreciate your help.

1. I would like to align center to the page the single thumbnail but I can't seem to make it work.
2. I have tried making the thumbnail dimensions bigger but I believe the plugin is creating temp files somewhere on the server and I need to delete them because I see a white border around the thumbnail. How can I solve this issue?

An easy way i can recommend to solve the first issue is to add in your css width:100% to the ul.sig-container-single class and at the li.sig-block class make the float:left; float:right; and add padding-right:235px;
It should work if you continue to have the same use of SIG Pro, for example if you continue having it centered in the page and as long as it's one thumbnail.

For the second issue besides the white border you also see a gray one 1px and a shadow, right? 

thank you. It worked like a charm :-)
