slideshow plugin devpress does not resize tall images to fit my gallery

my wordpress.com site would do resize large images that are tall to fit into a slideshow box.

This link is for my .org site, which shows the slideshow, with the picture of a guy playing guitar which is supposed to show down to his feet however. https://mylesok.com/aarc/2011/11/03/144/

This would be automatically fixed with the wordpress.com slideshow. Devpress’s slideshow doesn’t do this and their editor isn’t user friendly to my experience level. Can anyone recommend a fix for this while using this plugin, or a known gallery that already does this?
