First of all, I'm not drawing a frame and then importing an image into it; rather, I'm simply placing an image, adding a keyline, then setting the text wrap. So, how is there even a frame to select vs. selecting the "image itself"? When you place an image, InDesign automatically creates a frame for you that is the same size as the image. It is not possible to have an image with no frame in InDesign. Second, why would one create a frame (unless they don't have the image yet and need a placeholder) vs. importing the image and doing what I've described. Just as you said, a frame might be created before placing an image because they need a placeholder. Another reason would be that they want to set the fitting options before placing an image. For example, lets say that the original size of the image is larger than the frame you want to put it into. You could create a frame, go to Object > Fitting > Frame Fitting Options, and choose an option. Third, if there IS a frame, how does one select it vs. selecting the image itself? (I imagine it is a matter of holding down a control or alt key but how do you know what you have selected -- the frame or the photo -- and how do you tell, to start with, that there is even a frame to select? In my case, there may not be since I know I'm not drawing any frames before I place my photos. To select the frame use the black Selection tool. As you hover your cursor over the frame a disk icon should appear in the center of the image. If you click the disk icon, the image instead of the frame will be selected. Alternatively, you can click the image with the white Direct Selection tool to select the image instead of the frame. Another technique is to double-click the image with the black selection tool to toggle selecting the frame and image.
