All I can say is that it’s possible he was shot already when that pic was taken but it doesn’t look like it. From the start that pic has intrigued me for the fact that it is so fuzzy that it looks like a water color painting. Is that because it was taken long distance in poor light? I don’t know.
About that pic of him climbing into/out of the boat... I don’t have it saved to look at it for comparison, but does it have any blood on it like these color photos do?

There’s another photo in 50 or 51 of that thread, right below 47 somewhere.
