When I tested to send an e-card to my email, I never get the picture displayed correctly. I always have to click on the link
"If the e-card does not display correctly, click this link"
When I right click on the undisplayed picture to see its properties, the Address (URL) is always missing one character (randomly) which caused the picture not displayed correctly.
Changing the themes (even the default) did not help.
You can try to send an e-card to your email address to test at:

Thanks for your help.
