Uploading Photos from Shutterfly for the Weekly Assignments

[Laz-E Acres_16]

I've recently joined DPS, and have taken interest in doing the weekly assignments. My photography website is on Shutterfly.com, and unfortunately, there are no help topics on how to upload photos from shutterfly onto DPS. I've tried uploading the picture from my hard drive, and when I click on the attachment link, the page comes up blank. I've tried copying the URL into the "Insert Image" pop-up, and still THAT doesn't work. I created a Flickr account for the moment, but I would really like to only have one photography website.

Are there any members on here who have worked with Shutterfly before? Any suggestions?
