If this happens, try connecting to Wi-Fi or moving to an area with better signal to see if that solves the problem. Since your photos will still be there if you leave the app or switch to another Gig, you can take your time to find an area with better signal. If that still doesn't work or if you can't move to another location easily, you may text those images or info to Support.
If you need additional assistance, you can contact us via chat on the website.
