how do you get the corners of your picture like this?

Follow this tutorial.

can you do this on paint?
i dont have any photo programs.

If you have a steady hand you can use the selection tool to cut out the corners, otherwise (depending on how many pictures you want done) I could do them for you.

moved to graphics help

You'll get more help in graphics help with this question, and since it doesn't apply to myspace, it doesn't really fit here.

i want to like have a program so i can do them all the time?
is there any programs that dont take up to much room on computers

You'll most likely need some type of photo editing program if you want to do it the easy way. There is a way to make rounded corners in paint , but I don't know if you can use that to help with the image. Otherwise do what Dee (WHIMSICAL 0NE ) suggested.

You can check the space amount on gimp, thats another graphic program.

i have GIMP now
how do i start to make my pictuures look like that?

wooot
wooot again
and again...
uhm. i have gimp 2.2. there are many ways to achieve rounded corners. you can either use paths and make it hard. you can make the rounded square and use it like a mask. use can use blurring and leveling. or you can just go to effects-->decor-->rounded corners. that is, only if you have a base layer and no extra ones on top.

If your really lazy..or just want some quick borders try using this link. Upload your photo. Go to DRAW at the top and then under ROUNDED BORDER. It's not the best..but it works.
