While centering images can result in lovely, symmetrical designs that make my AR/OC heart happy, placing things off-center and edgy often makes a more visually interesting card. Such is particularly the case with large images, like the one I'm using today.
WHAT NOT TO DO:
In the first example, the flower is only slightly off the edge. Less than a fifth of the image, in fact, is hanging off the edge: just the edges of two petals. It looks weird and accidental and sort of floaty.
With a roundish image like this one, it's better to have about a quarter to a third of it hanging off the edge.
WHAT TO DO:
See the difference? The bottom card looks settled, with the flower hanging more decisively off the corner, like I meant to put it there. The center of the flower is roughly in the lower-left sweet spot (that magic place where the lines dividing the card into thirds intersect). The sentiment balances it in the upper-right sweet spot and has a bit more room to breathe with the flower situated slightly lower.
As an added bonus, if you mess up as on the first card, you can always trim the card down a bit on the left side and bottom. That way, if you have perfectionist tendencies and are bothered by the slightly off-kilter feel of it (raising hand here!), you can change it, and no one is any wiser.
I'll have several more posts with advice for stamping off the edge, with examples of what to do and what not to do. Hope this helps!
