... If you don't want to look at it, don't click on it.
And how would I know if I want to look at it if I do not click on it?
Once I clicked, it is
an imposition if I had to wade through, say, hundreds of crappy images (or even hundreds of fantastic images). It takes my time, to say the least. I would be tempted to go to the bottom of the post just to get an idea what the point was, or if the poster has a question (after all, this is a discussion forum, not a gallery). If I find I did it in vain, I most likely would refrain from clicking on the same poster's future posts, especially if there is a pattern.
Now put yourself in the shoes of the poster we are talking about (not Chris, just a rhetorical one): if he is smart enough he will realize that posting that many (or simply crappy) images will
result in other forum members shunning his future posts.
It all simply boils down to a good taste, common-sense, and politeness.
On a practical side, if the poster is looking for comments, especially for comments on individual images, it makes it rather impractical to post more than a few in the same thread.
