Problem with previewing images. (Not site issue, just on my pc)

FWIW: I sometimes have this very problem. I have noticed a pattern to it though. When the network load of the server gets to a certain point, I start noticing some interesting behaviour, including this very issue.

Simply put, when the network load level gets too high, not only does this very thing happen for me, but I often get random "Network Error" messages pop up here and there. In some cases, there is even a delay in the pages loading, and it seems that it takes some time to actually process the request and begin to render the content.

Perhaps this issue may be in intermittent issue related to the network demand of the server? Specifically, due to the high load levels, there is a delay or in some cases, even a time out that occurs, resulting in the content not displaying as intended?

@Joker have you heard about this? The frequency at which this happens is often not consistent. I only finally put 2 & 2 together on this issue when I ran into a situation where instead of getting delays (among other strange issues), I actually ran into a full page error message about the network load level being too high. It was a "too many requests" page that more or less said that the page could not be retrieved because the network load level was too high, though I don't get this message very often. Sometimes, the problem lasts all day, while other days, it only happens here and there once in a while, but then goes away. The "Network Error" messages are most common in the messages app.
