_expires
Sets an expiration timestamp for this API call.
Default Value
None.
Remarks
This parameter is required for some advanced API scenarios. Most API users can
safely ignore this parameter.
_expires is typically set to some time in the relatively near
future. Time is encoded as "Unix time" —
the number of seconds elapsed since January 1, 1970 (UTC).
_expires is often used with _sig to
create a secure, time-limited URL for accessing the Picnik API.
