Please add this to the Custom CSS area in  Theme Options - General Settings:


-------------------------------------------

body.single-post .image-post-format .post-media {

  display: none;

}

---------------------------------------


This will hide the media for the image post post format. Feel free to list additional formats in the css selector.


If you want to hide the image used in standard posts as well, you can use this code:


--------------------------------

body.single-post .image-post-format .post-media,

body.single-post .standard-post-format .post-media {

 display: none;

}

----------------------------------------
