Needs sharper images – BannerPic - Post Photo Banners On To Your Instagram Wall Review

I bought the full version of this app and it's great for splitting photos for Instagram. My only issue is that once a single photo is blown up to fit 6-8 square photos, it becomes a bit blurry or pixilated. Is there something you guys can do to improve the pixels or focus on each individual photo once split into several?
