I agree with the OP - photos often don't give any additional information and may not have "helped" with this problem.
In fact, if the frame / slide are galled, you could take the gun apart and photographed the rails and probably would not have seen the problem.
Galled areas often do not clearly show up as they are so small - yet, they will stop the gun from cycling. I have had two guns with galled slides / frames and you could not see the problem without a 10x magnifier.
The Internet penchant of "show us pictures so we can see the problem" is more akin to voyeurism as there is more to speculate and discuss with pictures. More speculation doesn't equate to "help."
