Vectors (illustrations) are extremely versatile. Not only can they be enlarged in size without quality loss, but they also make wonderfully creative photo frames. The trick, however, is to import them into your Photoshop document as a Smart Object by choosing File > Place. Navigate to the EPS file on your hard drive, click Place, then resize it using any of the automatically provided corner handles. Press Return when it's just right, then Command or Ctrl click that layer to load the illustration as a selection. Turn that layer's visibility eye off, select the layer of the photo you want to frame and add a layer mask by clicking the circle within a square icon at the bottom of the Layers palette. Poof! The photo automatically takes on the shape of the illustration.
