I don't have a Facebook account, but at least on the logged out ​http://facebook.com/ page, the "Block element" context menu item is shown for images.

It looks like that the OP of that forum thread didn't right-click an image but a container element, we never showed the context menu item for. You have to use "Block element" from the icon popup to block those.

In that case (of OP) is true: he wants to hide some html element (an entire zone) not only an image.
I tried blocking only an image and does not work (the option in the context menu is not present).
When I click the image (to open it) then on the opened image the option will be present.

I had an old test FB stuff (saved by some user), and you can see there, right click on the images in the page (scroll down) does not show the block element option

They use an interesting trick to hide images from the mouse pointer, applying following CSS on the image's parent element:

._4-eo::after {
border: 1px solid rgba(0, 0, 0, .1);
bottom: 0;
content: '';
left: 0;
position: absolute;
right: 0;
top: 0;
}

This essentially means that the image will be covered by an invisible pseudo-element. Hence mouse events will be dispatched to the image's parent element instead. Note that not only our "Block element" context menu item is missing, but also the built-in "Save image as" and "Copy Image URL" items.

yep, right, "save image as.." is missing, I noted as well ... so, it's normal behaviour. Thanks.
