Answer 14 · 2019-05-16T06:28:31.000Z

Hi,

There is a problem with gmail, because of security reasons it will not accept the zip file. It assumes that there is a malware so it will not pass it.

you can use Lightshot (screenshot tool) it is a chrome/Firefox extension for taking screen shots of the screen and convert it into shareable link.

Thanks,
Chandni
