Doubt about images in Latex

\begin{figure}[h!]

    \graphicspath[scale = 0.2]{/Desktop/Universidade/2017li1g013/relatorio/Imagens/haddock.png}

I want to insert an image from a directory. However in the PDF does not appear the text that I placed to find the image. What is the error that I am making?
