The downside of the popup comment pictures is that it happens quite often to add a new page using one of those pictures: to do so I always have to click and open it in a new browser page now as I need to copy its link. Not so handy anymore if you ask me.
How were you doing before?
Did you do a simply click and after copy the address go back to the page?Otherwise you can still right click on the thumbnail and chose "copy link" (or "copy target" or something like that, depending on the browsers), as before. Even with the added javascript popup the link at HTML level as not changed.
Or just right click on the enlarged image displayed in the popup and chose "copy image link".
I could easily add a "copy link" button in the popup, if it is handy.
