ATD/IS creates the Analysis report with the needed screenshots. The hyperlink for the screenshot is generated as a
local reference. For example,
<img src="/results/2018-04-17/698/10663.jpg">, which works when the web server serves both HTML and image files.
The ATD/IS Manager of the primary node fetches the HTML report from the remote node and presents it to you. The web server on the primary node receives the original HTML report from the remote node and displays it without change. It doesn't update the link to the screenshot files to point toward the remote node.
For example, the link
<img src="https://192.168.10.10/results/2018-04-17/698/10663.jpg points to a local node
<img src="/results/2018-04-17/698/10663.jpg">.
