how can i add alt tags in slideshow ck?

for now do that
I will check again by my side where is the problem

Hello, i am trying to be w3c compliant so i need alternative text for all images in the slideshow. The thing is i have read this post and i have a title at every image but i still can't pass the test. In the generated code there is a div with the "camera_caption_title".
I am using version 1.4.54.

I don't know if i must have some other options on/off for this to work. I have "show The Caption" on so i dont know what else to do.
Can you please advise?
Thank you!

Hi
the images have the alt tag since long now
give me your url (to the page where I can see the slideshow) to check what could be the problem and paste me the error from the W3C
