OK, some context to the above image for those who haven't read the comics:
The regular SW comic series has now moved into the post-TESB era. Our heroes have returned to Cloud City: Luke to see if he can find his lost lightsaber, Lando to spring his buddy Lobot (who the Empire captured), Leia to return to the carbon freezing chamber and learn how to defrost Han once they find him. She gets caught by a pair of stormtroopers, and into the vat she goes. "I love this part," one of them says as she freezes. "Makes handling Rebel scum so much easier. Don't have to feed them, don't have to worry about them escaping."
The story's not done yet, and when Leia inevitably gets saved & thawed she'll no doubt have a nasty case of hibernation sickness/temporary blindness. Try rewatching her attempted rescue of Han in ROTJ with that in mind.
