Being a PHP and Zend Framework newbie, I wanted to put the blame on Zend but in the end I found the reason for the upload and validation errors after much googling.

The solution requires updating two properties in php.ini:

upload_max_filesize = 32M
post_max_size = 32M

With these changes you can now upload relatively bigger files!

Just make sure that your hosting provider supports your file upload size settings.
