When using the in-app share button to share images, a file called "image_proxy" is shared, not the image itself. This started happening for me when I switched to lemmy.zip from lemm.ee - I just tested lemmy.zip in Thunder and it works as expected, so seems to be some combination of server+Boost causing the problem.
Think you're a little mixed up with your time lines :). ADN is a 2 year degree. BSN is a 4 year degree. RN is a license, no specific timeline (other than having to obtain ADN or BSN to be eligible to sit for the NCLEX).
