URGENT - Images not showing/broken in inline emails

ZOHO email inline images are broken! Not showing inline! I encounter this problem since August 2018 and made contact with support{at}zohomail{dot}com and its not resolved since.

I'm forced to download the images 1-by-1 to be able to view it, and its really frustrated to communicate with our clients!
