Denis, it perfect ! Thank you ! Do you have something like Buy Me a Coffee ?

Denis, its almost perfect ! Picture is inserted, just resolution is not scaled down to thumbnail size, as per settings:

Is it possible also to make it show thumbnail of the selected size and if its clicked, then open new tab with full size image ?

Upmost thank you, Varshil – the idea worked, just needed to add a colon (:)
