Well, with respect, I reversed Cafeinlove's suggestion of setting an absolute value of 665px. Setting the outer table to a percentage width allows the most flexibility you're going to be able to get outta this box. If you set it to absolute width of 665px, it's going to easily break when you start putting large text strings into the individual cells, as in the case of these ridiculously long filenames.

But the truth is, even percentage widths will eventually break, if you put something big enough into the cell. On the talk page of the Wikia infoboxexample, I've just deleted the underscores on the file name, and the box is fine.

You have, as I see it, a few options here: GENERAL TECHNICAL INFORMATIVE
 * Reduce your pic size to 150px, and force it to always be 150px. The very fact that you're allowing pic size to be settable means that anyone could break the template by specifying, say, 500px as the pic width.  You need to take that option outta your users' hands.  Every infobox pic should be the same width.  By setting it at 150, you're giving yourself 100px more width, or thereabouts.  (But I don't think this is your best option.  Read on.)
 * Abandon the practice of including underscores to make one big, 100+ character filename
 * Keep your pics at 250px, but ensure that they're fixed at 250px. Then rearrange your content so that it's three horizontal "strips" of info:
 * In other words, make the General and Technical sections work like the Informative sections. This way, you'd be giving about 400-odd pixels of width for your filenames, and they probably wouldn't break the template anymore.
