Quick fix for validating images

Quick fix for validating images on ready.mobi

"Specify the width and height of images in pixels as attributes of the IMG element. This allows devices to leave space for the images when they arrive, which means that pages don't have to be re-drawn several times"

PHP Code:

function img($file){
list($width, $height) = getimagesize($file); $count = strrpos ($file, 'http://');
if($count){ $n=1; $alt  = str_replace('http://','', $file); $alt = explode('/',$alt); $alt  = $alt[0]; $alt = explode('.',$alt); $alt  = $alt[0];
}
else{ $n=2; $alt = explode('/',$file); $alt  = $alt[count($alt)-1]; $alt = explode('.',$alt); $alt  = $alt[0];
}
echo ".$file."' width='".$width."' height='".$height."' alt ='".$alt."'/>";
} ?>

PHP Code:

img('tools/logo.gif');//my pictures img('http://waperos.net/tools/logo.gif');//external url ?>
