Robot Framework - Selenium - how to check if image loaded completely

I want to check if an image is completely loaded on a page using Robot Framework. I've tried with two keywords

1. Wait for condition | return arguments[0].complete, //Image xpath
2. Execute Javascript | return arguments[0].complete | ARGUMENTS | //Image xpath

But these are not working. What am I missing?

I went through these two answers which are not specific to Robot Framework.

• Wait for an image to be fully loaded Selenium WebDriver

• Check whether image file exists, Robot-Framework, Selenium2Library
