Cropping Images in Illustrator
It's great that you can combine photographs with vector artwork inside Adobe Illustrator. But sometimes you might decide that you want to crop part of a placed photo. Do you then need to go back to Photoshop to crop the image? Heck no! Illustrator is quite capable of cropping placed images (as well as its own objects), and in fact offers several methods for doing so. For a simple crop, you can create a clipping mask from a vector object. You can create more complex cropping effects by using the Transparency panel, along with blending modes to hide parts of an image with an Opacity Mask. You can also create fades and transitions this way, by incorporating gradient fills in the mask.
To demostrate these cropping methods in Illustrator, Adobe Community Help and Learning's Erica Larson has posted the following YouTube videos. If you're new to cropping in Illustrator (or just need a refresher on the basics), they're well worth checking out.

In this video you will learn a quick and easy method for cropping images in Adobe Illustrator CS6 and CS5. Using clipping masks allows you retain the area of the image you cropped out as well as modify the clipping path later on.
Cropping Images with Opacity Masks
In this video you will learn a versatile method for cropping images in Adobe Illustrator CS6 and CS5. Using opacity masks allows you retain the area of the image you cropped out, modify the clipping path later, and use complex blending modes, transparencies, and knockout groups.
