Re: ALT Tag on World Map

[Jonathan Callahan <callahan@xxxxxxxxxxxxx>]

Robin,

The <image ...> tag in ui.xml specifies which image to use in the
LiveMap applet.  This is LAS specific xml and there is nothing in the
LAS code that understands an 'alt' property on the <image ...> tag.

I'm not sure why you want to add an 'alt' tag as the image is only used
in the applet.  It is never directly accessed by the browsers.  And
there is already an error message page that comes up for browsers with
java disabled.
