My last request for help had to do with making Amazon images clickable with my ID embedded in the image, and I appreciate very much the help I received.

Now that I've got the image on the WP site I'm working on, (my first WP site!), I'm not at all happy with all the white space that came with the image. The whole thing is one big block. My attempts to make the white block smaller by editing the image within WP have not worked.

Is there a way in Amazon that I can manipulate this image before I link it to Wordpress? Or do I have to upload to something like Paint first? And from there link it to my post?
