If this parameter is specified, Picup will return control to your app when the transaction is complete. It will be opened by Safari or whichever native app handles the custom URL.
Possible Values
Any escaped URL
Default Value
null
Sample Value
"http%3A//myapp.com/form.html" OR
"customscheme%3A//customurl"
Discussion
Because the return values can be very long, they are appended to
the callbackURL as a hash value, not a query string
(e.g. http://myapp.com/upload_complete#foo=bar&status=Complete).
This allows Picup to circumvent some web
server URL length limits.
If the URL uses the "http://" scheme, Pickup will open a new window
in Safari rather than returning control to the window that launched it.
For this reason, it is recommended that the callback page be transient,
rather than opening a second copy of the first window.
The parameter name of the image POSTed to the server. This is useful if you're using a server other than imgur, but should not be changed if you're using the default postURL.
These parameters will be POSTed to the upload server along with the image. This is useful if you are using a server other than imgur and you need to pass along information such as a user_id or API Key. Passing in ANY value for this parameter will override the default imgur API key.
Possible Values
Any escaped string of parameters formatted as a GET query string.
Informs the user what the image request will be used for. This is useful in the case that an upload is unsuccessful (e.g. offline usage) and the user later resumes the upload.
This favicon for the App requesting a file upload. This is displayed in the context of a specific upload.
Possible Values
The escaped URL of a favicon.ico file, or a favicon in data:URL format (escaped).
Default Value
The imgur favicon
