Hi all I'm looking for some replacement code for the following

Code: Select all

$fileList = $this->getFileList();
			$imageMaxRatio =  $this->imageMaxWidth / $this->imageMaxHeight;
			$numFiles = sizeof ($fileList);
			echo ("<table width=100%>");
			for ($i=0; $i<$numFiles;)
			{
				echo "<tr>";
				for ($cols=1; $cols<=$this->maxcols; $cols++)
				{
					$out ="   <td align=center>";
					$imageFileName = $fileList[++$i];
					if (strlen($imageFileName)>0)
					{
						$imagePath = $this->pathToGallery."/".$imageFileName;
						$imageSize = GetImageSize ($imagePath);
						if ($imageSize)
						{
							$imageWidth = $imageSize[0];
							$imageHeight = $imageSize[1];
							$imageRatio = $imageWidth / $imageHeight;
							if ($imageRatio > $imageMaxRatio)
							{
								$imageOutputWidth = $this->imageMaxWidth;
								$imageOutputHeight = ceil ($this->imageMaxWidth/$imageWidth*$imageHeight);
							}
							else if ($imageRatio < $imageMaxRatio)
							{
								$imageOutputHeight = $this->imageMaxHeight;
								$imageOutputWidth = ceil ($this->imageMaxHeight/$imageHeight*$imageWidth);
							} else
							{
								$imageOutputWidth = $this->imageMaxWidth;
								$imageOutputHeight = $this->imageMaxHeight;
							}

							$out .= "<a href=\"".$imagePath."\"";

							// check to see if link to open in a window or not
							if ($this->window ==1){ $out .= "target=\"_blank\">";}

							$out .= "<img src=\"".$imagePath;
							$out .= "\" width=\"".$imageOutputWidth;
							$out .= "\" height=\"".$imageOutputHeight;
							$out .= "\" border=\"0\"><br>";
							$out .= $fileList[$i]."</a>";
							echo $out;
						}
						echo "</td>";
					}
				}
				echo "</tr>";
			}
The above code creates a table of thumbnails from a given directory. My problem is that the resizing of the iages takes place client side. and if the dir has a lot of large images, this can take a very long time to download and display all the images.

I'm looking for a method of resizing the images (jpg/jpeg/gif/png/bmp) server side, before they are send to the client, and if at all possible without copying/resizing the origanl image on the server or using gd. Just create the thumbs dynamicaly when the script is called, then remove them when the script ends.


any ideas?
