I will try to explain. I've just started using it too so I am far from being an expert.
In your photo library, double click on the image that u want to work on.
In the table on the left where you do the editing there is a tab labeled "effects." Click it.
Under effects in the bottom row, 2nd from right there is a icon labeled, "focal black and white." Click this and there will be a color circle w/ pointer on the pic.
Move it around until u have it where u want it. Use the size/saturation to play around until u get it the way u want it.
Hope that helps.
Thank you for the comments. I always get nervous sharing things for the first time and appreciate it!

Can you tell me how to edit them like that on Picasa? I've looked at the site but have no idea how to do that!
