  1. <form enctype="multipart/form-data" method="post" action="image_upload_script.php">
  2. Choose your file here:
  3. <input name="uploaded_file" type="file"/><br /><br />

Se supone que es exactamente lo que quiero, insertar un dibujo que se me visualiza junto con una marca de agua (no hay strings, pero supongo que no costaría nada ponerlos). El problema es que no consigo que se me suba bien el dibujo sin un maldito mensaje de error, y eso que hay un video explicativo y todo aparte que he visto, pero yo veo que está todo igual. No quiero hacerme pesado, si tengo que ofrecer dinero lo ofrezco, 20 o 30 euros, pero es que llega un momento que ya no sé qué sustituir por qué, si sustituyo el uploads por mi directorio de destino da los mismos errores. Necesitaré alguien que me explique las cosas como los niños pequeños (y pensar que he sido capaz de entender cómo se hace un blog multinivel con bases de datos relacionadas y todo, pero es que con la movida esta del GD no puedo).
