We will be uploading our HelloUpload video tutorial later today. We will let you know once it has been uploaded.
For now, download HelloUpload, open up your FTP program and on the root of your Magento store, upload the app folder, you also however need HelloThemes extension, do the same steps with the HelloUpload.
Go to the backend of your Magento store and you will see a module called "HelloThemes". Please remember for HelloUpload to work you need to have changed your server settings with the file php.ini, If you can't get access, just ask your hosting provider. If you have access to this file simply read the php.ini instructions over at HelloUpload.
Hope that helped for the time being.
