I have been working on some code for a while and I have almost finished but I have 2 small problems. When I run my code the line drawn when you click and drag wont draw on top of the yellow circle, I need some way to fix this, also I was wondering if there was a way to make the line drawn thinker or skinnier?

So far I have written a code for my project that is almost what i want it to do there are just some minor problems. I would like to be able to draw on the yellow circle but for some reason the circles wont draw on the bigger circle, my second problem is when you drag the mouse and draw circles if you draw to fast it has a delay and you get white spaces I would prefer to just have one solid line of black. If anyone knows how to solve these problems it would be greatly appreciated.

Is there a way to make the background an image from the internet, I know how to do it if the image is already on your computer but I have to send the code of my assignment to my teacher to view and she will not have the image on her computer so I need a way to keep the image as my background even if the code is sent to someone else.

Hi, I just started using code last week and I am working on a project involving processing. So far this is my code but I was wondering if someone could show me how I could get my circle to draw when the mouse is clicked/ held down for a period of time. My goal is to have the circle draw on the screen and then once you press the space bar it erases the screen and you can start your drawing over again.
