When an image is placed inside an
<a> tag resizing the image does not work as expected
The image can not be resized back to the original size (screencast). Its width can not be changed.
In case the image is set to float on the right after resizing its width becomes about 10px and is almost hidden - Dojo
It should be possible to resize the image by increasing/decreasing the size and keeping the width/height ratio.
