Joomla custom user extension - php

Question

I'm writing a Joomla 1.5 extension for an advanced frontend user interface.
Now I have to add a function so the users can upload a picture in the frontend and it will be added to their account.
Is there a standard Joomla picture upload available or something?
Thanks

I have this is my code: (and some more I can not paste everything in here)
function deleteLogo($logo)
{
// define path to file to delete
$filePath = 'images/stories/members/' . $logo;
$imagePath = 'images/stories/members/image/' . $image;
// check if files exists
$fileExists = JFile::exists($filePath);
$imageExists = JFile::exists($imagePath);
if($fileExists)
{
// attempt to delete file
$fileDeleted = JFile::delete($filePath);
}
if($imageExists)
{
// attempt to delete file
$fileDeleted = JFile::delete($imagePath);
}
}
function saveLogo($files, $data)
{
$uploadFile = JRequest::getVar('logo', null, 'FILES', 'ARRAY');
$uploadImage = JRequest::getVar('image', null, 'FILES', 'ARRAY');
$save = true;
$saveImage = true;
if (!is_array($uploadFile)) {
// #todo handle no upload present
$save = false;
}
if ($uploadFile['error'] || $uploadFile['size'] < 1) {
// #todo handle upload error
$save = false;
}
if (!is_uploaded_file($uploadFile['tmp_name'])) {
// #todo handle potential malicious attack
$save = false;
}
if (!is_array($uploadImage)) {
// #todo handle no upload present
$saveImage = false;
}
if ($uploadImage['error'] || $uploadImage['size'] < 1) {
// #todo handle upload error
$saveImage = false;
}
if (!is_uploaded_file($uploadImage['tmp_name'])) {
// #todo handle potential malicious attack
$saveImage = false;
}
// Prepare the temporary destination path
//$config = & JFactory::getConfig();
//$fileDestination = $config->getValue('config.tmp_path'). DS . JFile::getName($uploadFile['tmp_name']);
// Move uploaded file
if($save)
{
$this->deleteLogo($data['oldLogo']);
$fileDestination = 'images/stories/members/' . $data['id'] . '-' . $uploadFile['name'];
$uploaded = JFile::upload($uploadFile['tmp_name'], $fileDestination);
}
if($saveImage)
{
$this->deleteLogo($data['oldImage']);
$fileDestination = 'images/stories/members/image/' . $data['id'] . '-' . $uploadImage['name'];
$uploadedImage = JFile::upload($uploadImage['tmp_name'], $fileDestination);
}
}
