When you've made a graphic with rounded corners etc, it is nicest if the picture is transparent. I've made this, and want to have it transparent online.
1. Go to File > Save for web, as you see here.
2. A window will open. Choose similar settings as mine. Click OK, and choose a filename.
3. When you upload it, it'll be like this! (And as I've discovered lately, it's often much better if you just save it as PNG).
