Are they your photos? Looking at the code, it's a picasaweb gallery. I didn't know that would work here:
<font face="arial"> </font><div id="text-5" class="widget widget_text"><font face="arial"> </font><h2 class="title"><font face="arial">Photo Gallery</font></h2><font face="arial"> </font><div class="textwidget"><table style="width: 194px;"><tbody><tr><td style="background: transparent url(http://picasaweb.google.com/f/img/transparent_album_background.gif) no-repeat scroll left center; height: 194px; -moz-background-clip: -moz-initial; -moz-background-origin: -moz-initial; -moz-background-inline-policy: -moz-initial;" align="center"><a href="http://picasaweb.google.com/dnp1972/NLBroctonCoppiceCollieryGround"><img src="http://lh5.google.com/dnp1972/R30_HLIMStE/AAAAAAAAAUU/Vk6dB7W8d7Y/s160-c/NLBroctonCoppiceCollieryGround.jpg" style="margin: 1px 0pt 0pt 4px;" width="160" height="160"></a></td></tr><tr><td style="text-align: center; font-family: arial,sans-serif; font-size: 11px;"><a href="http://picasaweb.google.com/dnp1972/NLBroctonCoppiceCollieryGround">NL Brocton - Coppice Colliery Ground</a></td></tr></tbody></table>

What does it say on your Widget page? Do you have a text widget there, or what? Staff were tinkering with widgets a couple of weeks ago, but I thought they were done by now.
