I would like to ask you for advice as for using the longdesc tag in html img tag.It turns out that this tool http://wave.webaim.org is saying that the longdesc attributes for the img tags of my site do not contain an url. I do not understand that because they do conatin urls. However, after that I have seen some places like http://en.wikipedia.org/wiki/Longdesc_attribute where it is not very clear whether it is good to use it or not. So, now I am wondering how to fix the problem in case the tool http://wave.webaim.org is right or otherwise whether I should remove this longdesc parameters from the img tags.
Thanks in advance

Reason: removing unnecessary links
The odds are you do not need to use them for the images in question and the TITLE attribute will suffice. Very rarely have I come across an image that would really benefit a lot from LONGDESC attribute.
In addition you have to consider whether you have supportive text within close proximity of the image, for example; within a descriptive paragraph near to the image.
