Image links in gmail are broken because of google\'s Image proxy (news1,news2). I can\'t load my site\'s images in gmail.
Actual image path is: http://sampleimageurl.
I had the same issue and I solved the problem hosting the images in my public server (http://mydoamin.com/img/images.jpg).
Next step responsive email displaying responsive images: CSS
@media only screen and (max-device-width: 480px) {
td.headercell {
background-image: url(images/header-650@2x.png) !important;
background-size: 325px 115px;
width: 325px !important;
height: 115px !important;
}
td.headercell img {
display: none;
}
}
