Slide show not reducing

Great plugin, but when my site is reduced from full screen (on a pc using windows 7) the image slides do not reduced. http://www.tie2dye4.co.uk
Has anybody else experienced this and if so was there a solution. My apologies if there is a simple a solution this is all new to me.

thanks
