Upload pic_file to Google photos/Picasa with curl; returns source image URL

picasa_upld.sh

#!/bin/bash
#  Upload pic_file to Google photos/Picasa with curl; returns source image URL
#
#  Usage: picasa.sh   -s SCALE -a ALBUMID -t PIC_NAME -u -r pic_file
#          -s SCALE    -- scale pic_file to SCALE% (with imagemagic's convert)
#          -a ALBUMID  -- if not given upload to default album
#          -t PIC_NAME -- picture name, if not given the same as pic_file
#          -u          -- print HTML fragment with URL to pic_file
#          -r          -- remove scaled pic_file
#
#  Note: Images larger than 2048 x 2048 pixels do not count towards Google
#        free account limits.
#        As the limit is low it is useful to reduce size of photos
#        which exceed 2048 x 2048 pixels.
