I still get an error 404 if substituting 'prt' (the name of your images folder in your screenshot) for images, eg:
This one cannot be because 'a1' belongs to 'viewer' not 'viewer2'... You can see 'a1' if you put http://www.ccsilk.net/viewer/images/a1.jpg
You mean I can have two 'index.html' and two 'gallery.xml' if I have them each in two different folders?
I changed names of 'index2.html' and 'gallery2.xml' into 'index.html' and 'gallery.xml' then change the path of 'gallery.xml' in viewer2 folder. Also, I rename 'prt'folder as 'images'.
here is some sources of 'gallery.xml' in 'viewer2' folder
As I've told you before, you can see the second gallery by clicking the logo on the top rightside.
even I have 'images' folder in 'viewer2' folder,
You'll see nothing when you open the second gallery.
Why do they cannot show these pictures?
