#!/bin/sh

#---Description:  webcamcollage.sh (aka farmcamcollage.sh) is a shell script to automatically move
#                       and capture images from the Trendnet TV-IP400W Wireless internet camera.
#                       This script was written to run on Solaris, but could easily be modified to run elsewhere.
#                       Solaris 10 comes with wget and the ImageMagick tools to create the final collage.
#                       This script uses "wget" to position the camera (CGI post) and wget to capture the image.
#                       ImageMagick is used to create a collage from the captured images.  The only added
#                       package needed, is the "mpack" tool to create the mime encoded email attachments.
#                       Future versions will include options to create a panoramic view of the captured images.
