I have been looking for a SmugMug plug-in for my WordPress Blog for the last 2 months and this is the one I have been looking for. It allows me to very easily add (embed) a link to one of my SmugMug gallery images in a WP post. I did not want to actually add the images to the WP Media files, so this is the perfect solution. Also you can configure details for the linked image such as the caption (use default or customize for this link) and what happens when image is clicked. Thanks very much and I hope you continue to develop and support this plug-in.
Enhancement Request: It would be great if I had an option for the image "click" link to have it open in a new window. Currently, clicking on the image takes the user away from the blog post and to the SmugMug site. Feel free to contact me for details. Thanks!
