Q: I love your app that I am testing now, just what I was looking for, but I cannot publish to my FTP Server and I need have to solve this issue. I got following error message: "Connecting to host failed: Host not found".

A: Are you able to connect by FTP using the same FTP settings in other FTP Manager?

Check also that you selected the created location from the list of available locations till you press Publish button.

Actually you can upload VisualLightBox gallery using ftp manager you usually use.
You should publish gallery on a local drive in any test folder:

- open Gallery->Publish gallery or click 'Publish' button on the main menu panel;
- select 'Publish to folder', click 'Browse' button and select any local folder;
- click 'Publish' button

Open saved folder you'll find index.html file with slideshow, "data" folder with images and thumbnails and "engine" folder with .css, .js, files.

You should upload all these files on your server.
