Subject: [PATCH] revert: revert feature about saving image as new file with
 different format.

This reverts commit 5b2255e903000a8b76606bdceee45b22fb01f95c.

The feature about saving image as new file with different format is not the goal of an image viewer.
There is no need to keep feature diversity in this fork.
So I simply remove it.
