I have images of varying sizes. I want them to be scaled prior to upload to
a set size of 300 x 200 px


$imageinfo = getimagesize($_FILES['userfile']['tmp_name']);

$ix=$imageinfo[0];
$iy=$imageinfo[1];



//upload the images script
I

That's nice.

Give a man a fish, he'll eat for a day. Then you'll find out he was
allergic and is hospitalized. See? No good deed goes unpunished....

Also, you need to bring in a calculation to resize this with the same
dimensions... otherwise you're going to skew your image. From one of
my classes that resizes images very abstractly, I have this (you'll
have to change the $this references to your image...)

/**
* get the sizes
*/
$oldX = imageSX($this->_image);
$oldY = imageSY($this->_image);


/**
* if old x is bigger than max s or old y is bigger than max y
*/
if ($oldX > $this->_maxWidth || $oldY > $this->_maxHeight ) {

if ($oldX > $oldY) {
$newX = $this->_maxWidth;
$newY = $oldY * ($this->_maxWidth / $oldX);
}


if ($oldX < $oldY) {
$newX = $oldX * ($this->_maxWidth / $oldY);
$newY = $this->_maxHeight;
}


if ($oldX == $oldY) {
//means they're a square
if ($this->_maxWidth < $this->_maxHeight) {
$divide = $this->_maxWidth / $oldX;
}
else {
$divide = $this->_maxHeight / $oldY;
}

$newX = $oldX * $divide;
$newY = $oldY * $divide;

}

}
else {
$newX = $oldX;
$newY = $oldY;
}


Now, when you resize, you should use your $newX and $newY so that your
image isn't skewed.
