how do you post a picture?
Two ways:
1. If the picture is under 256KB (or if you could resize it to that), use the built in uploader. Click "Reply" then click on "Attachments and other options". You will then see the option to choose a file to upload.
2. Upload image to any image sharing site. Paste the image link here with [img ] before, and [ /img] (without the spaces) after. You could quote any post with an image to see how it was done.
