Update of /cvsroot/phpwsbb/phpwsbb/imglib
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv17107/imglib

Added Files:
	ImgLibrary.php ImgLibrary_view_gallery.tpl 
	ImgLibrary_view_row.tpl README 
Log Message:
Patch #1002850, Eloi's changes.  Need to be tested and examined.

--- NEW FILE: README ---
This module uses a new core library that allows you to choose images from
an image gallery.

For it to work, you will have to move the included file ImgLibrary.php to
directory "/core", file "Image_Library.txt" to directory /docs/developers
and files ImgLibrary_view_gallery.tpl & ImgLibrary_view_gallery.tpl to
directory "/templates".
