MDB2 connet to multiple MySQL databases

If you connet to multiple databases MDB2 uses only the first db.
To fix the issue add "new_link=true" to the DSN.

GraphicsMagick and PHP
2007-08-11 by xpheas
I wrote a small command line PHP script using the GraphicsMagick library to scale down a lot of pictures.
The script creates a scaled down version from the original picture and a thumbnail.
Optionally the script can generate hyperlinks and bbcods.
First the PHP sourcecode:
Set up the config variables:
$dir_in - relative or absolute path to the pictures you wish to convert
$dir_out - relative or absolute path to the new pictures and thumbnails
$base_size - the new max picture size
$thumb_size - thumbnail size
Optionally - if you wish links and bbcodes:
$url - the full url (with ending shlash) to the folder, where the pictures are stored on the web.
$pics_per_row - line-break (<br />) after ?? pictures
If you don't have installed the GraphicsMagick library, you can install it under ubuntu
by typing "sudo-apt get install graphicsmagick". (the universe repository must be activated)
Usage - from unix shell:
Save the script i.e. as gm.php.
Make it executable - "chmod a+x gm.php".
Rund the script by typing "./gm.php"
