[Orgmode] underscores in img names

[Richard Riley]

has something changed in link publishing?

[[file:../images/ecb.png][file:../images/ecbs.png]]

this gives a text link as opposed to an image. I havent published for a
while so it might have been so for a while.

Looking at the html generated its of the form:

<a href="../images/gnus_scr.png">
<img src="../images/gnus
<sub>scrs</sub>
.png"/>
</a>

I know the file is there.

It seems the proper source file for the preview image is being rendered
wrong because of the underscore

"_"

In this case the src file was "gnus_scrs.png".
