-- SUMMARY -- Picture element Hide image ---------- If you use the '- empty image -' option, you have to add the following to your theme css to completely hide the image, otherwise it will still take some space. img[width="1"][height="1"] { display: none; } Warning: For now this CSS will not work until https://drupal.org/node/2280471 gets fixed. It is postponed until the upstream issues https://github.com/ResponsiveImagesCG/picture-element/issues/50 and https://github.com/ResponsiveImagesCG/picture-element/issues/85 are fixed. Meanwhile you can hide the image with css using breakpoints. See https://drupal.org/node/2280471 for more info.
