Hi there,
I've got this code for creating thumbnails, i'm not sure if it's what you're looking for but here it is:
function createThumb($imageDirectory, $imageName, $thumbDirectory)
{
$ext = strtolower(substr($imageName, strrpos($imageName, '.')));
if (($ext == "jpg") || ($ext == "jpeg"))
{
if(function_exists('imagecreatefromjpeg'))
{
$srcImg = imagecreatefromjpeg("$imageDirectory/$imageName");
$originalWidth = imagesx($srcImg);
$originalHeight = imagesy($srcImg);
$thumb_maxY_P="85";
$thumb_maxX_P="114";
$thumb_maxY_L="114";
$thumb_maxX_L="85";
$theRatio = $originalWidth / $originalHeight;
if($theratio<1)
{
$newWidth=ceil($thumb_maxX_P / $theRatio);
$newHeight=$thumb_maxY_P;
}
else
{
$newWidth =$thumb_maxX_L;
$newHeight = ceil($thumb_maxY_L / $theRatio);
}
$thumbImg = imagecreatetruecolor($newWidth,$newHeight);
imagecopyresized($thumbImg, $srcImg,0, 0, 0, 0, $newWidth, $newHeight, imagesx($srcImg), imagesy($srcImg));
$thumbname="thumb_".$imageName;
imagejpeg($thumbImg, "$thumbDirectory/$thumbname", 100);
}
else
{
$thumbname=$imageName;
}
return $thumbname;
}
else if ($ext == "gif")
{
if(function_exists('imagecreatefromgif'))
{
$srcImg = imagecreatefromgif("$imageDirectory/$imageName");
$originalWidth = imagesx($srcImg);
$originalHeight = imagesy($srcImg);
$thumb_maxY_P="85";
$thumb_maxX_P="114";
$thumb_maxY_L="114";
$thumb_maxX_L="85";
$theRatio = $originalWidth / $originalHeight;
if($theratio<1)
{
$newWidth=ceil($thumb_maxX_P / $theRatio);
$newHeight=$thumb_maxY_P;
}
else
{
$newWidth =$thumb_maxX_L;
$newHeight = ceil($thumb_maxY_L / $theRatio);
}
$thumbImg = imagecreatetruecolor($newWidth,$newHeight);
imagecopyresized($thumbImg, $srcImg,0, 0, 0, 0, $newWidth, $newHeight, imagesx($srcImg), imagesy($srcImg));
$thumbname="thumb_".$imageName;
imagejpeg($thumbImg, "$thumbDirectory/$thumbname", 100);
}
else
{
$thumbname=$imageName;
}
return $thumbname;
}
else if ($ext == "png")
{
if(function_exists('imagecreatefrompng'))
{
$srcImg = imagecreatefrompng("$imageDirectory/$imageName");
$originalWidth = imagesx($srcImg);
$originalHeight = imagesy($srcImg);
$thumb_maxY_P="85";
$thumb_maxX_P="114";
$thumb_maxY_L="114";
$thumb_maxX_L="85";
$theRatio = $originalWidth / $originalHeight;
if($theratio<1)
{
$newWidth=ceil($thumb_maxX_P / $theRatio);
$newHeight=$thumb_maxY_P;
}
else
{
$newWidth =$thumb_maxX_L;
$newHeight = ceil($thumb_maxY_L / $theRatio);
}
$thumbImg = imagecreatetruecolor($newWidth,$newHeight);
imagecopyresized($thumbImg, $srcImg,0, 0, 0, 0, $newWidth, $newHeight, imagesx($srcImg), imagesy($srcImg));
$thumbname="thumb_".$imageName;
imagejpeg($thumbImg, "$thumbDirectory/$thumbname", 100);
}
else
{
$thumbname=$imageName;
}
return $thumbname;
} else {
return false;
}
