Uploading Images to Guestbook Problem

When I first instaled the Guestbook it worked fine, but after customizing the style of my guestbook something happened and suddenly the feature of uploading images started to have problems.
It allows the user to upload the image, but when trying to see the results the image link appears broken and gives an error.......something like "Forbidden" that you do not have access to those files in the server.....something like that.

Does anyone know something about this

Here's my guestbook:
http://todomimundoacolor.com/guestbook/index.php

re-chmod the folder that contains the images to whatever it says in the readme file.

Chmod the files doesn't work.....I've Tried that.....
I get the same result, the image uploads.....I can see it if I enter my site via FTP but when I try to acces it from the guestbook still gets me the "forbidden" error.

Thanks anyway, I'll keep searching.

That's exactly what happened to me. Did you ever find a way to fix it?
