How to indicate your preview of the picture when writing a link in VK?

Question

HTML

Hello! Please help me figure it out.
When I insert a link to my site in VK, the picture that is on this site is automatically loaded. Please tell me, I can somehow specify in the html code which specific image should be loaded by default when someone writes a link to my site. I understand that I can choose a different picture or even upload it from a PC, but I just need to upload a picture from the site and at the same time, so that this picture is not on the site itself or it is hidden
That's what I mean
