Hello Amir,

I'm sorry for delay with reply.

We can do it as custom modification only, but current version of uploadify plugin can work on edit listing page (with small changes in code of flynax).
And also in there is new configuration which allows to remove add-photos icon on my listings page.
So you will able to manage images on add listing page and also on edit listing page.

Please create ticket and i can make the change for you.
