Grid_fullsize

Hi I have installed the gallery but the grid_fullsize is to big to fit in the webpage, I have changed all the css I can see and everything changes to fit except the main image?
how do I force all main image's to fit
about1.php

Thanks

If you add a width to the element's style area, you can change the width of the main image. Something like this:
style="visibility: visible; opacity: 1; display: block; margin-top: 0px; margin-left: -50px; width: 600px;"

Not sure where I would put this? common.css or index.php??

Think I have done it but any portrait are streched out to the 580 width making them very tall how can i stop this

Sorry, I didn't take into consideration botht he landscape and portrait layouts of images. Instead of adding the width, you should add max-width and max-height to the image:
max-height:500px;
max-width:580px;

It does appear you have added it to the correct place though.
