The zip file says "This image is split into multiple images"
These files total 72 mb and the individual files are 59mb and 19mb.
Weatherfax was designed and programmed to take small sized fax files <1mb from the Noaa and other
Weather websites, or via NOAA
radio signals and overlay them on regular
charts. It is very capable for this purpose. The plugin does not have adequate memory management to support such large files, in my opinion. It is amazing that it at least worked partially. Perhaps by resizing the files you can make them
work better.
As I suggested via
email earlier, review at the Advanced Chart tools under Supplementary Programs in the wiki. You may find some tools there that are useful.
