Take a screenshot of the item. Paste the screenshot into the paint program on your computer and cut out the section with the item. Cut and paste that section into a new paint window and save the picture as a jpg. Then edit your post or make a new one and go to "additional options" under the submit button. Go to the "attach files" section and click the button there. Click the "browse" button and find the image and then click the "upload" button to attach the picture of the item into your post. Hope this helps.
