In SageMath Cloud select "New". Type the name you want and click on "Sage Worksheet". The Sage worksheet opens up. Copy/paste the following code into your worksheet.

c = circle((1,1), 1, color='red')
c.save('test.png', xmin=-1, xmax=3, ymin=-1, ymax=3)

Click on "Save" and then click on "Run". It looks like nothing has really happened but if you click on "Files" you will see test.pgn.

If you click on the name of the picture (test.pgn) it will open in your browser. You can right click on the image and save it to your computer. Another option (instead of clicking on the picture name) is to click on the rectangle furthest left (on the same line as test.pgn) then a box opens up giving you options such as download, move,trash. Press download and it should go to your computer. If not there's a link to click, in which case you download as mentioned above (through right-click and Save as).

I had the same question and tried this. It worked (sort of) but the resulting image had been changed in strange ways, and also there is no option to rotate/zoom to the view you want. The picture I got from screenshot was much better quality. It's hard to believe this is not built into Sagemath- how does anyone use Sagemath for making high-quality illustrations for a paper or a book?

Not clear what you mean when you talk about "changed in strange ways". What's the strange behavior you are talking about? The option to zoom/rotate is for 3d images. Try typing G = dodecahedron(color='darkseagreen',opacity=0.2) G.show() After pressing enter, right click on the image. It will give you the options of zooming and rotating. When the image is how you want right click and export to a jpg file or some other image file. I've been able to get high quality images (such as fractals) by saving the image to pdf. You can also force the data through LaTeX using the sagetex package along with tikz/pgfplots to produce high quality illustrations.
