After a little experimentation it seems like the image ratio is respected when width or height is set in pixels but not when a percentage is used, for instance <img alt="Some image" src="some-image.jpg" width="25%" /> I use Dillo version 3.0.4 in Debian Jessie (stable). -- August

AFAIR, it was/could-be done this way by dillo (using CSS hints) but somewhere in the redesign (GROWS) these image-size hints were lost. @Sebastian, @Johannes, please correct me if I'm wrong here. -- Cheers Jorge.-

Yes, this is the right thing to do and is the only way images should generally be used on the web (since you always want uniform scaling and don't get it when setting both width and height, so only one of width or height should ever be set).

This is why it did not go into the release. I'm currently working on another approach to reduce these CPU hogging problems, which still orrur, see [1]; although there has not been much work recently. (And the "dillo_grows" version will not work at all.) The problems are caused by floats; so disabling them by adding * { float: none !important } into ~/.dillo/style.css should help.

Apparently some (or most?) browsers, Firefox for instance, do uniform scaling when only one of the width or height attribute is set on an img element. Dillo does non-uniform scaling and changes only the specified dimension. Here is what the reference has to say about it: "When the object is an image, it is scaled. User agents should do their best to scale an object or image to match the width and height specified by the author." http://www.w3.org/TR/html401/struct/objects.html#edef-IMG It seems to be a question of interpretation. -- August
