File size is always an issue when downloading such big content, so we always produce each Wikipedia file in three flavours:
Mini: only the introduction of each article, plus the infobox. Saves about 95% of space vs. the full version. nopic: full articles, but no images. About 75% smaller than the full version Maxi: the default full version.
