Viewing Images in Mass Emails

Viewing Images in Mass Emails

Hello,
I've created a Zoho Campaigns email using a template within Campaigns. I added 4 pictures using the template and just sent out test emails. The pictures don't show up unless the receiver clicks 'download'. Is there a way to make images show up without this step? It looks unprofessional with little red 'x's and a request to download. I would like clients to be able to open up the email and see all images and text at once. Please let me know if this is possible.
Thanks,
Marissa
