>_<

u can’t do this when someone add post
u need to save rotate position in db.
just only what can u do – rotate downloaded image in post
sry 4 my english. hope u understand me)

use jquery like this

var rotate_factor = 0;

function rotateMe(e) {
    rotate_factor += 1;
    var rotate_angle = (180 * rotate_factor) % 360;
    $(e).rotate({angle:rotate_angle});
}

<img src='blue_down_arrow.png' onclick='rotateMe(this);' /></a>

i use “Video Thumbnails” plugin
Which creates thumbnail from embed video and insert it like preview image.

When i “Add new post” this image insert in post attachmets.

If i Deactivate WPUF, Video plugin works ok.
