FTP Upload Using Web Browser
From myhosting.com Wiki
You don't need to have a special FTP client in order to connect to your site. You can use any web browser to connect by FTP. You can connect by typing the following address in the Address field of your browser:
ftp://username:password@ftp.domain_name.com:21
Make sure to replace username, password, and domain_name.com with your actual account username, password and domain name.
When you are first connected, your root directory will be displayed. You can move to any other directory/folder by double clicking on the folder name. You can browse each folder and upload or download files simply by Dragging and Dropping to or from the browser window.
Please note that depending on the web browser, you may not be able to write/upload, but only read/download when connecting this way.
