HG-416 Fix linked images being stretched in ADB

The images in linked images component got `width` and `height` set to `100%` while in our regular galleries their size is set to 195x195px. The `100%` didn't break anything in normal browsers but it made images stretched in Android Default Browser.

By removing the rules we're inheriting 195x195px rule for `img` tag and the stretched images are gone.
