php code:



// IMAGE WATERMARK (comment line below if you do not want to use image watermark)
Define('WATERMARK_IMAGE', './wt.png'); // path to watermark image
Define('WATERMARK_PERCENT', '100'); // Intensity of the transition (in percent)


// TEXT WATERMARK (comment line below if you do not want to use text)
//Define('WATERMARK_TEXT', 'SinglesPleasures.com'); // text to place (image will not be used)
//Define('WATERMARK_TEXT_FONT', '4'); // font 1 / 2 / 3 / 4 / 5
// Define('TEXT_SHADOW', '0'); // 1 - yes / 0 - no
//Define('TEXT_COLOR', '#FFFFFF'); // text color


// GENERAL SETTINGS
Define('WATERMARK_ALIGN_H', 'right'); // left / right / center
Define('WATERMARK_ALIGN_V', 'bottom'); // top / bottom / center
