Dynamic thumb size

You just need to play with the CSS file to change the size of the images. For example, I wanted the images to be smaller so I did the following:

#pinterest-pinboard-widget-container .row { width: 94px; height: 94px; }
#pinterest-pinboard-widget-container .pinboard img { width: 92px; height: 92px; padding: 0 2px 2px 0; }

The first line modifies the size of the row container, and the second line modifies the size of each individual image.
