//$img_anchor allows the browser to scroll down automatically to the thumbnails set or the image when given a unique name value.  This is especially useful in Drupal (or other CMS) installations where you might be displaying multiple photosets on a single page.  Non-critical if incorrectly implemented.

//$img_maxwidth indicates the maximum width a zoomed-in image may occupy inside the browser window.
$img_maxwidth = 640;
//$width_table is the table width suggestion for thumbnails list; normally overridden by css; you can write in styles like "480", 480, "100%" or 100%.

//$width_td is the cell width suggestion for thumbnails list; normally overridden by css; you can write in styles like "115", 115; I am not sure if percentages can be implemented here.

//$sscolor is used to specify the background color for the slideshow submission form
$sscolor = "#eeeeee";
//$slideshow_default determines the default number of seconds should elapse before the slide viewer advances to the next image page
