You can use borders as “frames” to help unify the photos on a slide or across your entire presentation. This technique is simple but useful. Of course, you will use your presentation color scheme/theme and size and crop your images appropriately (see previous post). Remember not to overdo this – you want consistency, not distraction. Here are some examples to inspire you.
Original image –
Outline color (use a line weight that can be seen, at least 2.25pt) – the examples show a solid and a gradient line –
Compound and dashed outlines –
Gradient rectangle “underlay” with a light line color on the original image (you could also apply a shadow to the image) –
Pattern filled rectangle underlay (you could also use a patterned line – missing in PowerPoint 2007?) –
Two-color underlay –

So – simple ideas to make the photos in your presentation more consistent with each other and with your color scheme. A touch of class.
