$model = Mage::getModel('modulename/modulename');
$model->setData($data)->setId($this->getRequest()->getParam('id'));
try {
if ($model->getCreatedTime == NULL || $model->getUpdateTime() == NULL) {
$model->setCreatedTime(now())
->setUpdateTime(now());
} else {
$model->setUpdateTime(now());

$model->save();
if(isset($_FILES['image']['name']) and (file_exists($_FILES['image']['tmp_name']))) {
try {
$uploader = new Varien_File_Uploader('image');
$uploader->setAllowedExtensions(array('jpg','jpeg','gif','png')); // or pdf or anything
$uploader->setAllowRenameFiles(false);
// setAllowRenameFiles(true) -> move your file in a folder the magento way
// setAllowRenameFiles(true) -> move your file directly in the $path folder
$uploader->setFilesDispersion(false);
$path = Mage::getBaseDir('media') . '/modulename_images/' ;
$uploader->save($path, $model->getId().'.jpg');
$model->setImage($model->getId().'.jpg');
$model->save();

// Mage::getModel('modulename/flatrates')->saveMultipleFlatrates($data, $model->getId(),$this->getRequest()->getParam('cat_id'));
Mage::getSingleton('adminhtml/session')->addSuccess(Mage::helper('modulename')->__('Item was successfully saved'));
Mage::getSingleton('adminhtml/session')->setFormData(false);
if ($this->getRequest()->getParam('back')) {
$this->_redirect('*/*/edit', array('id' => $model->getId()));
return;
}
$this->_redirect('*/*/');
return;
} catch (Exception $e) {
Mage::getSingleton('adminhtml/session')->addError($e->getMessage());
Mage::getSingleton('adminhtml/session')->setFormData($data);
$this->_redirect('*/*/edit', array('id' => $this->getRequest()->getParam('id')));
return;
}
}
Mage::getSingleton('adminhtml/session')->addError(Mage::helper('modulename')->__('Unable to find item to save'));
$this->_redirect('*/*/');
}

In order to get the image preview, you have to use the image field type, not file, like this (look at second parameter):

$fieldset->addField('image', 'image', array(
    'label'     => Mage::helper('modulename')->__('Image'),
    'name'      => 'image',
    'note' => '(*.jpg, *.png, *.gif)',
));
