You may want to bypass the stage where cssSlider saves your slideshow to your computer and instead upload your completed slideshow directly to your FTP server. You will need to know your ftp address, username and password to use this functionality.
To do set it up, follow these steps:
Click on the 'Settings' button at the bottom of the right sidebar (the button with the 'gear' icon) to open the 'Settings' panel.
Click on the 'Publish' tab at the top of the settings panel.
Tick the 'Publish to FTP' checkbox.
Click on the 'Edit' button next to the FTP drop-down. A window called 'FTP Location Manager' will open.
You can add as many different FTP server locations as required.
After you apply the changes, the next time you publish your slider it will be uploaded directly to your FTP Server.
