This should be the clue. The question is -- how does the button tag know
when to display an image and when to display text?

It is simple. It tests to see if the file for the image exists; if it
does, then it uses the image. If it doesn't find the image, it shows the
text version instead of what it things will be a broken image.

The way it knows where it should look is from a concatenation of the
Variable value DOCROOT, the catalog.cfg directive ImageDir, and the
image name itself. It puts those together, stripping off any /~user/
component in front of the ImageDir, and sees if that file exists. If it
does, it shows the image. If it doesn't then it uses the text version.

My guess is that DOCROOT doesn't correspond to where your HTML/image
files are.
