If you want to surround an image with an anchor tag <code><a></code>, then you should add
a <code>usemya</code> attribute within the image tag or else your anchor will be ignored
and replaced. If you do not want the popup effect at all, add a <code>nofx</code> attribute
to the image. If you do not want any caption, you can specify <code>nocap</code>, or just
leave the title blank. And to have the plugin completely ignore an image and
output the content directly from the post, use the <code>asis</code> attribute.
