My original image is 144 x 144. The dimensions for the large thumbnail in my template are 658 x 435. Instead of blowing the image up to a really huge dimension, I was hoping to just scale it to only 288 and then have a border fill out the rest of 658 x 435 pixels. Is the plugin supposed to be able do that? I was unable to scale the image up or generate a large thumbnail...with or without a border. I just get an image of an exclamation point for the large image. How can I generate the large thumbnail? Thanks.
