here we list the possible statuses associated with an individual photo. You can see a Photo's status by calling Photos (GET)

AwaitingUrlOrData
There are two ways of uploading a file to Pwinty. You can either specify a url when creating the photo, or you can POST to /Photos using a multi-part upload. If you see this status, it means you have done neither yet for this photo
NotYetDownloaded
You have specified a url associated with the photo, but Pwinty hasn't yet downloaded it. There's nothing you need to do about this
Ok
We've received your image, verified it is a valid jpg file, and all is ready to go
FileNotFoundAtUrl
We tried using the url you specified to grab the image associated with the photo, but we didn't find an image there
Invalid
You uploaded a file, but it wasn't a valid jpg image file, or we checked the url you specified and didn't find a valid jpg image there
