Unable to View images in html report

hi ,

I downloaded ReporterForUipath.Activities package and also receiving mails with attached html report but on clicking image in report ,I am unable to view images of the screenshot.

Note : I am already checking take screenshot checkbox while using step status activity.

Please let me know if we need to configure anything in smtp activity properties section to view images in report.
UIpathStudio Version : Studio Pro 2020.10.6

Thanks in Advance,
