xemacs and emacspeak

I got emacspeak going under Xemacs.
it appeares that the file that the compilation was looking for existed
under a slightly different name.  This fixed, the compile worked fine.

the only problem that I have come accross is:
in w3 because the images are now displayed, tabbing skips over them
alltogether.  Even if they have an alt text tag.  is there a way of
getting emacspeak to read out the alt tag even if the image is
displayed on screen?
