Missionary Splits

Here's a gag featured in this month's New Era. Perhaps confusion like this moved the vernacular from missionary "splits" to missionary "exchanges".

And now for some insider business: Today is a day I've been dreading for months. Google has finally forced me to move from their old Blogger interface to the new one. I like all the features with the new one except when it comes to uploading images. As you can see above, Blogger no longer uploads images to completely justify the width of the posting area. Do any of you know how to fix it  so that images are fully justified?
