Test dim Img:
<form action="" method="POST" enctype="multipart/form-data" name="form_1" id="form_1">
<input name="immagine" type="file" />
<input name="submit" type="submit" value="Invia" />
</form>
Img:
<form action="" method="POST" name="form_2" id="form_2">
<textarea name="dim_img" cols="20" rows="4"></textarea>
</form>
</body>
</html>
Come posso mettere a video i valori (w,h) dell'immagine nella text area din_img, vorrei poter visualizzare i valori in modo da testare l'effettivo funzionamento dello script
