[Seaside] Still Unable to Display an Image

[dirk newbold]

Thanks Michel,

All perfect now.

I think I know why it didn't work when you emailed me that piece of code the
last time - I think I tried it after I went into the config page and pressed
submit, thus changing the default Home Directory without me realising
it.  Seems
I know just enough to make myself dangerous.

Thanks Michel (and All) for your help and patience - also thanks for the
further explaination on the configuration of sites it really helped further
my understanding of the Seaside framework.

Cheers,

Dirk
