Unfortunately not.
As I wrote in How to find the inaccessible links on a webpage - #20 by kazurayam , I wanted to find out if the keyword checks <img> elements or not. The portion you showed above does not tell it to me.
I needed to read the source of WebUiBuildtInKeywrds.getAllLinksOnCurrentPage() in full detail. I found that the implementation of this method is further modularized, I needed to go deep into the bunch of modules. And eventually I could not find the code which is actually scanning a web page for so-called “links”. I would be glad if you point me to the URL of that portion of code.
