In detail:
On the VK site, there is a need to replace the image in poor quality ( #pv_photo img ) with a picture whose address is indicated in "View original" ( pv_more_act_download ), the problem is that until you hover the cursor on the "More" button , the page does not create the pv_more_act_download element. It is necessary that this element was created without unnecessary gestures.
The goal, like the problem, is rather stupid, but I have been sitting for half a day already. There were attempts to find a function that works if you hover the cursor, there were attempts to look for ways to automatically move the cursor to this element. But my knowledge in this area is terrible, and my hands are crooked, so it only remains to ask for help here.

#pv_photo imgandpv_more_act_download) is indicated in the question text. - Qwertiy ♦
