It's a fairly simple process to post pictures.
Select the Full Editor and Preview button to create your post. There is a Tab near the bottom of the window called Attachments. Select it. A button to Add Files will appear. Click it. It will open a folder on your computer. Navigate to the photo, select it and click the Open Button. When the filename appears, you can select to Place Inline. This will put the image in your post where your cursor is positioned. If you add a File Comment, it will appear as a caption for the photo.
Photos that have a 4:3 ratio (640×480, 800×600, 960×720, 1024×768, 1280×960, 1400×1050, 1440×1080, 1600×1200, 1856×1392, 1920×1440, and 2048×1536) should not appear distorted. It's best to choose 800x600 for photos on the web. If you do post a photo that is long and thin, you'll have better results if the long side is the height.
