OK, try this very crude approach, which may need serious polishing:
Code:
awk -F, 'NR==FNR {Ar[$1]=Ar[$1](Ar[$1]?"|":"")$2;
                  if (!Rr[$1])Rr[$1]=$2; next}
         {for (i in Ar) gsub (Ar[i], Rr[i])}
         1
        ' file file1
<!-- group 0 -->
<img src="13429.png" />...text...<img src="13429.png" />...text...<img src="13429.png" />

<!-- group 1 -->
<img src="14136.png" />...text...<img src="14136.png" />...text...<img src="14136.png" />...text...<img src="14136.png" />
