How to post a picture

Sorry if this is wrong place to post this, wanted to show pictures of my work table I made for my 1F like others have done, but not sure how to do it. Can someone explain it to me?

When making your new post, look for the ‘upload’ icon - dark rectangle with arrow pointing up, 7th from the left. You can then ‘choose file’ from your device or the web. That is the method I usually use.

Thanks TMToronto, here goes.

Excuse the mess, just need paint, electrical, and the 1F LOL not due till late June, think I got plenty of time.
