A Question about Posting "Similar Images"

I've notice that some contributors have had images rejected for being too "similar" to other images they have posted at the same time. But I've also noticed that there are a large number of images "similar" to others have also been accepted, sometimes as many as three or four taken, for example, at different distances, or at slightly different angles, or with a variety of expressions on a models face, etc.

With that in mind, say I have an image of a model that might work well on a blog related to costmetics, skin conditioners, retaining a youthful appearance, or along similar lines. One is a head-on, centered portrait, while another (perhaps even the very same image), has been expanded to include room for some text on the left- or right-hand side. Is it reasonable to submit both images or would I be wasting my own and the moderators time to submit both? It's always difficult to assume the expertise of a potential buyer when it comes to editing an image for their intended use.

An example is attached and thanks in advance for your advice!
