Will the
seaside location/key of a file that has been uploaded as a
"file" in Pier be guaranteed to be static? For instance, can you
always be guaranteed that a photograph that was uploaded be
guaranteed to be at that address?
Yes, in the same way that other Pier resouces are static. If you
move a structure around, change the Seaside or Apache2 setup or
stuff it will break.
Pier produces REST-ful and static URLs for all its structures,
including resources/files. As long as you don't move the structure it
is bookmark-able and you can send the link around.
Example, this
is a photo uploaded to pier:
http://www.<my_domain>/?_s=BGrhMyNQYJbYqctY"
Can this link be used to resize the photo and be guaranteed not to
change?
No
Pier doesn't resize photos by default. There are extensions, like the
mentioned Pier Image Gallery, that provide support for that.
Cheers,
Lukas
