It looks like I can't make it to work. All the other properties are properly interpreted.
Any confirmation or ideas to sort it?
Thanks a lot, chr
I was forgetting, Gmail asks correctly to download the images, but after I accept, nothing happens.
Background images aren't supported in gmail, so you're out of luck.

Thanks for the info.

Long story short though, background images can be used, just prepare your email to function ok without it.
