$dir = "images/";
$handle = opendir($dir); 

while (($file = readdir($handle)))
{ 
     if (($file!=".")&&($file!="..")&&($file!="thumbs.db"))	
     {
         echo "$file";
         if (!file_exists($file)) 
         { 
            echo "Error: could not find file: $file."; 
            exit();
         }

     {
         echo "$file";
         //here lies the problem you're reading the images directory
         //which resides under the current directory and then looking
         //in the current directory for the file I will comment out the
        //bad code and replace it with good code
//         if (!file_exists($file)) 
         if(!file_exists($dir . $file))
         {

            exit();
         }

$dir = "images/"; 
$handle = opendir($dir);  

while (($file = readdir($handle))) 
{  

     if (($file!=".")&&($file!="..")&&($file!="thumbs.db"))     

     { 
         echo "$file"; 
         if(!file_exists($dir . $file)) 
         {  

            echo "Error: could not find file: $file.";  

            exit(); 
         }
         //
         //another error part 
         $img = "$dir$file";
         $tmp = imagecreatefromjpeg($img); 
         //i got an error message on the line above, saying 'unable to open the file for reading...'
      } 
.....//some other buggy code 
}

i tried like what you've advised me to,
but it's giving me a big error msg window
"PHP Script Interpreter has encountered a problem and needs to
close. We are sorry for the inconvenience." :eek:

i never got any error msg this big...what could be the problem?
this thumbnail creation is confusing me sigh

i know i don't have a solid ground on php, this whole thing has been like a crash course for me... :o

thanks again

daniel

it's something in your code that you haven't posted yet.

the reading from directory is ok now, now my problem is because the thumbnails aren't showing up.

i've posted a new thread...
