creating custom patterns
i have a ps book that has an exercise in it for creating a custom pattern. it has me go to a website and download a chili pepper. then i am suppose to open that up in ps, use the marquee selection tool to select the white background. then i am to go up to the menu and choose select --> inverse and it's suppose to select the pepper. then i am suppose to hit the the mask tool (bottom right layers panel). problem is when i go to choose select and then inverse - it tells me no pixels are selected. my layer is unlocked, i've tried finding another picture and downloading as a png. same problem. any idea what i'm doing wrong? thanks karen
