Beginner Photoshop Question

[c073186]

Okay this should be very easy but I cannot figure it out. I have pictures of CD covers but they are surrounded by a big white border. I want to get rid of this white border and make the CD cover image the entire image. So I go into Photoshop to do this but I cannot figure out the easiest way to reduce the canvas size to exactly what the image size is. I know I can copy the image and create a new image from clipboard size but that seems like too much work when I should be able to just reduce the canvas size of the original. I know I can do Image>Canvas Size adjustments but that is too much guess/check work. Isn't there a way to just use the selection / pointer tool to drag the canvas size smaller? It won't let me do that because my layer is locked. How do I unlock it? Sorry guys I know this is probably the stupidest most basic thing but I just can't get it.

No need to use Photoshop. Open the images in Preview. Select the acutal cover and press CMD + K

file > automate > crop and straighten photo's is meant to do this with scanned photofiles an should work for what you want.

Use the Crop tool (keyboard shortcut C). Drag the marquee around the cover and press Return.
