I'm designing a responsive wordpress theme and iwant to include a full page slider for featured articles. It should cover the whole screen of the index page on any device. However, the big problem is, that i would always need to create 3 versions of every featured image (for PC, tablet and smartphone) in order to make it look good. Is there any easier way, that doesn't require always 3 versions of every image, but still looks good full-screen? Has anyone of you ever had similar issues?
Thanks for any tips,
