not all WP9xx models had ethernet, but some did...
As stated, didn't put much effort in checking, but could only find references in that http part... that doesn't mean there isn't a magic keys/knobs combination, although it's less probable, as this would mean the reference to the image would use another 'base address' and use some offset to the image... not impossible, but rather unusual... (why would the http part reference it directly, while other code pieces would play around with a base address and some offset...)
