[RESOLVED] Thumbnail - one quick question

baffled_in_UK

I use the following function to create a thumbnail from an image just uploaded :

function resizeImage($filename){
   list($width, $height) = getimagesize($filename);
       $newwidth = 100;
       $newheight = 100;  

   $thumb = imagecreatetruecolor($newwidth, $newheight);
   $source = imagecreatefromjpeg($filename);
   imagecopyresized($thumb, $source, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
   return imagejpeg($thumb);
}

This code works fine. My problem lies in how to then get the generated image onto my server ? I don't know what function to use.

I am peforming the function "resizeImage" immediately before I do a "move_uploaded_file" on the original file.

Any help is much appreciated.

You want to save the image, or just show it?

It's possible to simply write a script, say, "thumb.php", which takes an argument (say, the image's filename), performs the resizing and outputs a JPEG header instead of an HTML header, then outputs the data. You put this URI in the HTML <img> tag as the "src" attribute, and, wham! ... instead thumbnail.

The function imagejpeg() also takes a second argument to output to a specific file:
[man]imagejpeg[/man] ( resource image [, string filename [, int quality]] )

Specify the output file, and wham! ... instead thumbnail in a folder!!

Sorry Dale... had to jump on that opportunity...

Nothing to apologize about. I don't do much with images, anyway; and why miss a good teaching opportunity? 🙂

Dale, I wasn't apologizing about the image thing, I was apologizing about making a joke about you:
