The problem may be the way you are putting $$row_f1['prom'] , if you realize these by putting a plus price sign.
I advise you to avoid these problems, assign them to a variable before opening the conditional. Example:
$rowf1 = $row_f1['prom'];
if ($rowf1 >= 5){
echo 'Es mayor o igual a 5';
} else {
echo 'No es mayor o igual a 5';
}
So you avoid having to write something long and tedious as $row_f1['prom'] every time, and it gives more clarity and readability to your code:)
My two cents here are to optimize a bit the code displayed, the error should be the one explained by Hoose (I will base myself slightly on his answer) and A. Felipe Trujillo:
<?php
// almacenamos el valor a evaluar en otra variable
$valor = intval($row_f1['prom']);
// usamos el último valor posible como valor por defecto
// para obviar un condicional
$salida = 3;
if ($valor >= 11) {
$salida = 1;
} elseif ($valor >= 4 && $valor < 11) {
$salida = 2;
}
// agregamos el valor resultado a la parte de texto resultante que no cambia
echo "<img src='img/btn$salida.png'>";
Because the function intval takes the whole part of a number, I do not see the sense that in your code you have intval(($row_f1['prom'])) <= '10.9' only with placing intval(($row_f1['prom'])) < 11 is enough
