[Typo3] Gallery in source

[Floyd Arguello]

Hi all,

When I view source for my site, I see the following listed:
#tx-lzgallery-pi1-listing 
{border-style:dotted;border-width:1px;border-color:#00008c;border-collapse:collapse;font-size:12px;padding:0px;font-family:verdana}
#tx-lzgallery-pi1-listing tr.line1 {background-color:lightgrey;color:black;}
.... several more lines follow

These blocks are listed twice, but I'm currently not using Gallery. How 
can I remove these lines?

Thank you,
Floyd Arguello
