Code Optimization/Allowed memory exhausted

LSArcher

I have written a image database for a photojournalist in PHP + MySQL. All worked out fine, but after exceeding 600 or 700 images, a Script started to make Problems. The Script is used to browse the Photo directory for new Pictures, resizes them to a small preview, and a medium preview which also gets a copyright stamp there. After resizing 8 Images the Script stops for two Seconds, and starts over again looking for the next 8 new uploads.

I am not sure if the Provider has changed anything, or it is the Scripts fault - after the last upload of Images i get the Error code: Fatal error: Allowed memory size of 8388608 bytes exhausted at (null):0 (tried to allocate 6396 bytes) in /home/www/web671/html/cms/resize.php on line 51

The Line Number differs sometimes

Beside asking the Provider tomorrow, i would like to optimize the Code anyway, because using 8 Megs seems quite a lot to me. Can anyone take a look at the Code Snipplet, and give me a hint how i could get this done? I've tried a few Tweaks (like resizing just 1 or 2 images per reload...)

Thanks for reading, Greetings - and i would be glad to get some help

The Essential Part of the Script (without the reload action, just it's break)

{

					$a++;
					if ($a > 8)
						{	break;	}
					printf ("<font><span class='bold'>$file<br></span></font>");
					$imageInfo = getimagesize($file); 
					$width = $imageInfo[0]; 
					$height = $imageInfo[1];

					$im_neu=ImageCreatetruecolor($width,$height);
					ImageCopyResized($im_neu,$im,0,0,0,0, $width,$height,ImageSX($im),ImageSY($im));

					printf("<font><span class='bold'>thumb$file</span> in der gr&ouml;&szlig;e $width x $height wurde erzeugt<br></font>");
					ImageDestroy($im);
					ImageDestroy($im_neu);
					$imageInfo = getimagesize($file); 
					if(!isset($s)) $s=15;
					$width = $imageInfo[0]; 
					$height = $imageInfo[1]; 
					$width = round($width/6);

					$im = ImageCreateFromjpeg($file);
