Lebel the next, previous, close button for the screen reader users

Hi,
Let me convey my gratitude first for resolving my previous issue where there is a letter “F” at the end of the page. I am glad to know that, it is fixed in the next version.
Now, here is another minor thing to fix. when there is a FooBox displaying an image, we are getting link/button like “Next” “Previous”, “Close”, etc. But it is not properly labeled for the screen reader user. I am not a PHP guy, so cannot tell you the actual solution. but there should be some kinds of tag or label field where we name the role of the button/link.
Kindly fix it in the next version.
