I understand but it can be fixed regardless of traffic. It is matter of good webdesign and to put a fallback situation.
Tell to your web designer that it is a 5 minute fix. I would fix it for you, if I would have access to the code.
You could solve the problem by setting the div setting where you apply the background image of the paper, adding a background colour like cream or white.
When the image is not loaded, the background colour will be loaded.
The mistake is that you have a BLACK BACKGROUND and BLACK TEXT, so when the image doesn't load, it is impossible to see any content.
I think that the div is ".postbitlegacy.postbitim.postcontainer" to apply a background-color:#fff; before the image declaration or together if you are using shorthands css.
(I know that you are looking for web designers, but come on, it is really less than 5 minute release changing a CSS file... It doesn't cost a thing to open a bug report with my suggestions, or just walk down to a table of someone in the office and say: "hey there is one line of code to add!")
