Imagus (atleast how I've used it) just pops up an image if you hover on it. Imagus removes the extra crap when showing you the pop up.

This seems to be if you are given a link to an "image" it displays only the image and not the extra crap.

Are you able to use imagus on the phone? I love imagus too, but the images in this app seem to convey that this is meant for opening imgur links on mobile.

Imagus (never heard of it before) is apparently not on Safari while this one is only for Safari.
