I am trying to upload a picture of N131VR Ranger R7, when I add the picture then click on the field for the registration the profile is there but when I try to proceed the box no profile exists would I like to add a new profile pops up, any idea why this might be happening?

If you have viewed the profile, and clicked on "Have a photo of this aircraft?", the registration box should be auto filled. May I suggest that you resize the image to 1024 pixels width so the whole image fits screen size.
