download image from remote source and resize then save

Question

Do any of you know of a good php class I can use to download an image from a remote source, re-size it to 120x120 and save it with a file name of my choosing?

So basical

Answer 1

You can resize keeping the ratio of image

$im = imagecreatefromstring($img);

$width_orig = imagesx($im);

$height_orig = imagesy($im);

$width = '800';

$height = '800';

$ratio_orig = $width_orig/$height_orig;

if ($width/$height > $ratio_orig) {
   $width = $height*$ratio_orig;
} else {
   $height = $width/$ratio_orig;
}
