Hey guys,
Sabrina contacted ryan and he said that if it is impossible for you to upload make sure to bring in your flash drive with you image as well as all of your source images on it. If you do so I think you s hould be ok (also you have to have your print... duh) but do that and I think you'll be ok.
Hope this helps!
Madeline
p.s. if you have time and you can contact ryan and double check with him
