[accessibleimage] Re: SVG maps

Hi Dave,

Since the maps are for the screen I wasn't thinking about a screen reader.
But that of course should be considered.

Yeah I have heard about the text label and thought about that because of a
limitation there seems to be with the number
of wav files I could have in one svg file. I'm not sure if this is
correct, but seemed only able to get in 21 wav files. Seemed
a bit strange. Googled a bit to see if others had also found this. So
still unsure if this is a restriction or a mistake I am making.
Do you have any idea?

Could you send me an example of the text label or a link about it? 

Thanks,
Lisa
