I have been trying to add the alt="[some text]" attribute to my image 
thumbnail links for accessibility purposes (as opposed to the "tooltip" 
text, which in html code is title=[some text]), but nothing seems to be 
working - when I save the tiddler, the alt text is not there. Ideally I 
would like to include it in the image link macro I use (as described here 
<https://groups.google.com/forum/#!msg/tiddlywiki/JU6yf1MNDHM/otpA1fDTlZgJ>) 
if possible, but nothing I have tried is working, such as:

\define imageLink(url,image,alt)
<a href="images/$url$" target="_self">[img alt="$title$" [$image$]]</a>
\end

I was trying to use the tooltip as the alt image, but it gets messed up 
when rendered in the html code, and the image does not display:

<a target="_self" href="images/image.jpg 
<view-source:file:///F:/My%20personal%20stuff/Creative%20stuff/Star%20Warrior/Tiddly/images/adept-biologist-veil.jpg>"><img
 alt="$title$" title="image" src="images/tn-image.jpg 
<view-source:file:///F:/My%20personal%20stuff/Creative%20stuff/Star%20Warrior/Tiddly/images/tn-adept-biologist-veil.jpg>"></a>


I have no idea what I am doing, so I'm stuck!
