Unfortunately, MediaWiki has a hard-coded image limit and this is beyond that limit. From the help files, it seems that the post size cannot exceed 8 megabytes. I would try to drop the image below that threshold.

Also, as far as that goes, 8 megabytes is huge as far as wiki standards. Most images are sized down regardless when used on a page. I would strive to size the image down the 'normal' sized usage and keep at that size -- that way the thumbnailer doesn't even have to alter the image.
