This is from Donghae were revealed at his and Eunhyuk’s: D&E “Hello Again” Fanmeeting today.
It seems like this photo of Yunho is indeed from when he went to Changmin’s favourite bakery and visited him as reported on March ~

(from the periscope broadcast by @Iidonghais)
Donghae said that before Yunho hyung was discharged, our (Super Junior) members had also come to visit many times but Yunho hyung had not come once. Then before he was discharged, he came to visit Changmin and brought along delicious food with him.
