I dunno where you plan to put the AJAX part...
upload.php
<?php
$destination = "/path/to/some/directory/I/can/write/";
//untested code:
if (isset($_FILES) && count($_FILES)){
if (move_uploaded_file($_FILES['image']),
"$destination/$_FILES[image_name]"){
echo "<img src=\"thumbnail.php/$_FILES[image_name]\" /><br />\n";
}
}
?>
<form action="<?php echo $_SERVER['PHP_SELF']?>" method="post"
enctype="multipart/form-data">
Upload an image: <input type="file" name="image" /><input
type="submit" value="Go" />
</form>
thumbnail.php
<?php
$destination = "/path/to/some/directory/I/can/write/";
$filename = substr($_SERVER['PATH_INFO'], 1);
$image = imagecreatefromjpeg($filename);
$width = imagesx($image);
$height = imagesy($image);
$thumb_height = round(50 * $height/$width);
$thumb = imagecreatetruecolor(50, $thumb_height);
imagecopyresized($thumb, $image, 0, 0, 0, 0, $width, $height, 50,
$thumb_height);
$thumbfile = str_replace('.jpg', '_thumb.jpeg', $filename);
imagejpeg($thumb, "$destination/$thumbfile");
header("Content-type: image/jpeg");
imagejpeg($thumb);
?>
You're on your own to add the error checking, test the error setting
of $_FILES, validate the image to avoid being a warez site, handling
goofballs who name their .jpg files as something else like '.jpeg', or
handling other image formats or...
But, really, it's not exactly a complicated script...
