How to post on the VKontakte wall for a user?

Question

API

Colleagues, hello!
Task: the user on the site attaches a picture, presses a button, confirms the access rights and the picture that he chose on the site + accompanying text is fasting on his wall.
I know that work with the wall is closed for the Authorization code flow.
How to solve my problem? What type of application to choose and what algorithm to build?
Thank you!

If your task is virality and the purpose of posting on the wall is not functional, then you can try using the comments widget with the autoPublish = 1 parameter. With this parameter, the checkbox for publishing a comment on the wall will be automatically checked.
True, the checkbox remains in the interface so that the user can uncheck it, but with simple manipulations it can be covered with a small div-block with css properties z-index:999 and position:absolute; (although I do not recommend doing this, somehow grayish).
In exchange for a comment, you can offer some kind of bonus or service. It seems to me that it would be much easier for you, if of course this decision is appropriate for you.
