I'm on a slow connection, but these are fairly small (<300k) images.
With "Send to Smugmug" the status bar sticks about 80% for a while, then the upload fails.
With Olde Faithful, the "Upload status" animated window never goes away on its own, and the "Don't close this window" window eventually goes to "The webpage at
http://upload.smugmug.com/photos/new_add.mg might be temporarily down or it may have moved permanently to a new web address."
Trying a single ~200k file with Olde Faithful, it errors out after a few seconds, and the upload log shows "Wrong bytes received."
