This is often not tried by many as it is considered the most difficult of all. As most of the techniques go to a different level for hiding the text, when the image is kept inactive that signifies that nothing is being showcased, which is not good. It means the text needs to be displayed.
- The other test of CSS remaining off and images ON signifies browsing without stylesheet has been applied. Most of the techniques being applied by default to the usual web text on such occasions don’t fail. However, as the images may still be kept active, this is not considered a safe option.
