The workflow for OTRS image submissions would be pretty much the same
as if someone emailed them to you in your normal email client. They
come as attachments, which the worker would have to remove to their
local computer, and upload like normal. The OTRS system does have
canned message replies, but they have to be chosen, and sent. There is
no integration with wikipedia/commons of course.
It does have work queues, and the idea of people being assigned to
emails, which is probably nice for this. Also, I haven't looked at the
emails in this queue, but I can almost guarantee people aren't sending
all the required licensing information in the first email,
necessitating followups etc.
I don't have a really strong opinion either way, OTRS would probably
be better for the followups, and queueing, but it might be nice to
select a license from the a dropdown, select the attachments, and
click upload also... :) If you were a little more strict in what
needed to be in the email (licensing) maybe a toolserver system would
work. Declined messages could say what they are missing, and they
could just try again. OTRS is usually a little more hand-holding, and
that may be a benefit in this situation to some people.
