Just trying the Photo Testing site:
Modeling HO with a transition era UP bent
Well, copying the BBCode the Medium works better! Nil ill effects created.
OK, now try flickr Medium 640x480

Above has some cross-hatch effect also. Trying here the flickr option again, but this time choosing the Large 2048x1536 (vs.Large 1024x768 option used above).
Posting the forst photo again, except from flcikr. The imgur version shows incorrect cross-hatching and I want to see if flickr avoids that.
The first was imgur, this one is flickr:
