Some Raiser's Edge NXT users may find that a profile photo they're trying to attach to a constituent profile won't upload. They may try multiple times, but it looks like nothing happens. They may report that profile photos on other constituent profiles have uploaded normally, and that Raiser's Edge NXT is working fine otherwise.
Remove any non-alphanumeric characters from the file name - anything that isn't a letter A to Z or a number 0 to 9 - and reattempt the upload.
Example: Change gregg?popovich.jpg to greggpopovich.jpg.
