Adding a label to graphic inside a longtable

There are multiple images in my long table environment, however I could not find a way to correctly label all the images in this long table.

setcounter{ltrow}{0}
setlengthLTleft{-1cm}
begin{longtable}{c m{2cm}@{hskip 15mm} m{5cm}  m{4cm}}

multicolumn{1}{c}{Authors} & 
multicolumn{1}{c}{Configurations} & 
multicolumn{1}{c}{Observations} & 
multicolumn{1}{c}{Image}

  label{Table:paper-matrix}
end{longtable}

This gives the following output, where each paper is aligned one below other, as follows,

Now, if I do a label{Bozzoli20} under the first image after includegraphics, the number associated to label{Table:paper-matrix} is shown instead, for all the images that have been respectively labeled.
Could anyone point to another method? I essentially want to refer to each or one of such images, and not the table.

I checked these answers but are for captions, so did not work.
