I read your answer (about https://www.nextscripts.com/support-faq/#a15) and noted above – it’s not useful.
Problem is in VK.COM sending Image, other networks have’t that problem.
Now made Test posting, (Image Post mode, Post format is: %TITLE%
%URL%
%EXCERPT%
%IMG%
%HTAGS%),
result the same – see scrennshot of post on VK.COM

In Log/History:
“..[2017-05-15 23:12:56] – [Posted] [VK.Com – VK_Compas] – OK – Message Posted Test for the snap Image Post mode | Post Link..”
Image not posted, what & where to do now ?
