The url of the image somewhere online. Any image hosting service will do. I like https://postimages.org/. You might have to play around with the output size so it's not too big on the forum page. Free service, no login needed.

Can't remember if that used to work here or not. Clearly the image button requires an existing online url and not a local filesystem reference.
Thanks from zylo

To attach an image, use the Go Advanced button (or Alt + X on a PC) and then scroll down to see the Manage Attachments button, etc.
Thanks from Maschke and zylo

Thanks Maschke, Skipjack, and Romsek (Latex forum)

Almost there, but can't straighten it out even though I rotated original jpeg image twice. Will try taking picture 90deg. For now, this is the best I can do.

Below I've attached a slightly smaller version of your image, so that it orients properly.

However, this doesn't improve the correctness and quality of your sketch and the equations given. Those equations would be better omitted, and instead typed using latex markup in the post.

If you make a Google image search for a cardioid graph, the top hit is a reasonably accurate graph for the equation given for the cardioid in this problem. You can superimpose a circle and hatching or shading of the relevant region by use of the MS paint image editing utility.

Been playing with orientation, and a more detailed sketch.

EDIT
Skipjack, why don't you show us the sketch using your method.

How I finally managed to post picture right is in my here:

Another option. Want the third?

EDIT WHAT! Picture came out sideways. It must be in the cropping (right picture cropped).

I've done that already, in this post.

I think what you meant is rotating the image. How did you do it?

MS Paint allows image rotation as well as editing. MS Windows Picture and Fax Viewer can also rotate an image.

So does the editor in Windows 10 that a jpeg image opens up into. That's where I cropped it, which did come up right in post.

How did you do it?
