To select the image you want to post, Click "Choose File". You can browse your hard disk to find the image file.
Click "More Attachments" to post as many as 4 images in one message.
The usual formats can be posted with jpg as the most common.
Be careful of the image size. Today's cameras can take photos that are too large to be seen conveniently on a computer monitor. A large image can be attached to a message but it will be difficult to view as it will more than fill the monitor and entire image cannot be seen at one time.
Best size for a typical image is to have the largest dimension about 650 pixels or maybe 850 pixels. Photo software can reduce a large image or the camera can be set to take the photos at about the 650 size so re-sizing is not necessary.
