When composing email in mailpress, email is sent with both gray placeholder and original image, which looks add. I believe it worked perfectly before last plugin update

It seems you are reading the code of the page to do the lazy load instead of what is actually in the view port. In wordpress the sidebar is included after the content. So any images is my sidebars do not show up until you have scrolled to the very bottom of the page.

We need some sort of sidebar fix, or use the real viewport opposed to code.

just to report that the plugin is not working with the latest WP version :)

Best,
M.

PS: Hm... after delete & reinstall - it seems to have start working again...
weird.

I enable WP_DEBUG on a client's website (http://seointhemaking.com) and there's an error that says:

"Undefined variable: class_attr in /home/_/public_html/__-_*/wp-content/plugins/jquery-image-lazy-loading/jq_img_lazy_load.php on line 57"

(server name & site subfolder name retracted for security purposes).

Is it probably for a incompatibility, or an issue with invoking $class_attr when linking an image?

Thanks.
