I just tried making a symlink to the /tmp/ramdisk directory, inside the
public_html directory, and that worked.
pi@pi3:/home/weewx $ ln -s /tmp/ramdisk /home/weewx/public_html/ramdisk
NOW the web server is able to pull the image from the ramdisk.
<!-- Radar image -->
<div class="col-lg-5 radar-map toprow-height">
<img src="./ramdisk/webcam-time.jpg" width="640"
height="480">
</div>
</div>
<!-- End of first row -->
