Martin Grigorov commented on WICKET-2192:
-----------------------------------------
Is this functionality really needed ?
As far as I know if there are no width/height attributes to <img> element then
the browser reads that information from the image and use it. Width and height
are needed only if you need to manipulate them or preserve the space before the
image is actually downloaded.
Check:

> Image should automatically set width and height attributes in markup

>
> org.apache.wicket.markup.html.image.Image component (and all possible
> derivates) should add width and height attributes of the image it represents
> automatically to markup to allow for faster correct rendering of the actual
> page. For example when rendering a table with images in table cells the table
> cell width may vary a lot during loading of the page and its contents which
> causes the table to jitter around while loading if image dimension attributes
> aren't set.
