как мога да задам примерно тук <img src="kartinka"> ако е повече от 300px широчината й, тя автоматично да става <img src="kartinkata" width="300px"> ..?

Това няма нищо общо с това което пита!!!

Код: 
list($width, $height) = getimagesize("".$promenliva."");
if($width > 300) {
echo "<img src='$promenliva' width='300'>";

}

и как да го вградя тук
Код: 
$text2 =preg_replace("/\[img\](.+?)\[\/img\]/s", '<img src="$1" alt="" title="" >',$text2);
 
list($width, $height) = getimagesize("".$1."");
if($width > 300) {
echo "<img src='$1' width='300'>";
}
else {
echo "<img src='$1'>";
}
Увеличете...

или

$image = $1;
list($width, $height) = getimagesize("".$image"");
if($width > 300) {
echo "<img src='$image' width='300'>";
}
else {
echo "<img src='$image'>";
}
Увеличете...

за това избощо не съм сигорен но пробвай ако не станат тези 2:
list($width, $height) = getimagesize("".$text2."");
if($width > 300) {
echo "<img src='$text2' width='300'>";
}
else {
echo "<img src='$text2'>";
}

нито едното не стана :?
 
защото като поставиш картинката и то я вкарва с <img src='...'> след минутка ще си едит поста :) и ще го направим :)


EDIT:
Код: 
$image = $1;
$img = substr("".$image."", -10, 2);
list($width, $height) = getimagesize("".$img."");
if($width > 300) {
echo "<img src='$img' width='300'>";
}
else {
echo "<img src='$img'>";
}

Така?
