Images are not showing up in campaign - HELP!!

Images are not showing up in campaign - HELP!!

QUESTION -  very frustrated here.  Two issues:
1 - I have sent 8 campaigns successfully to date with no issues.  Today I have had problems.  In each campaign I have uploaded the same image with my business logo.  Today, when creating the content, I upload the logo image.  It shows in the preview version, but when I do a test email, the images do not show up.  I've tried about 7 times to no avail.  The logo image is zipped etc but is not working.  Also, I am unable to send feedback to Zoho because when I type message and hit Send button, nothing happens.  What is going on today???
I had time sensitive breaking news but now it's too late.  I am not happy with Zoho today in the least.
Who can shed some light for me on this?  Thanks so  much.
