General Support: Broken Layout when individual pictures are clicked

Hello. I am new to Plogger and I have found it impressive. However I would like to raise an issue which I have been searching answers for.

I have integrated plogger into my website layout and while the layout looks ok when I access the thumbnails page, things go awry with the layout whenever the thumbnails are clicked in order to procure a bigger version of the image. Example of such here: http://edssjphotogallery.awardspace.info/?level=picture&id=13. I need the integrated plogger page to have a lesser table width so as to fit but I don't know where I could tweak the HTML. Also I tried modifying the default theme's (Classic) css file and I cannot seem to change the gallery links' font sizes.

I would appreciate any help you may allot me regarding my dilemma. Thanks.
