How to use
Copy Code code as follows:
Include ' Upimages.class.php ';
$max = "Upload"; File Upload Path
$mix = "small"; Thumbnail path (must be established under upload)
$mark = "Mark"; Add water to the picture store path
$text = Array ("Oktang", "2012"); Watermark Content
$img = new Upimages ($max, $mix, $max); Instantiating class files
$photo = $img->upload ("file"); Uploaded file fields
$img->maxwidth = $img->maxheight = 600; Set high, and wide
$img->tofile = true;
$NEWSMALLIMG = $img->smallimg ($photo);
$newMark = $img->watermark ($photo, $text);
Echo $newSmallImg;
Echo $newMark;
echo "<br><br> ';
echo "<br><br> ';
Note that there is a font file, you can download from the Internet.
