Gets or sets the upload restrictions.
public function getRestrictions() {
}
public function setRestrictions($value) {
}
All limitations specified here are checked client-side, so you should not interpret them as a reliable protection. A potentially malicious user can bypass all these limitations (by emulating Image Uploader Flash). That is why it is highly recommended to implement server-side verification of uploaded files in addition to Restrictions properties.
In other words, all limitation features discussed in this topic should be used solely for the convenience of the user. They should not be interpreted as a serious protection measure from malicious users.
