Edit your post, when the button asks quick edit or full edit, choose full edit.

Then below the space where you would type, there will be a box that allows you to chose attachments.

Once you have chosen a picture, and allowed it to load. You will see a button on the far right that allows you to insert into the text. Before choosing that button, ensure the cursor is where you want to insert the picture into the text.
