Many of the apps allow an image or multiple images to be added to a text. Surveys and Coupons do not allow images to be added but Texts, Polls, and Event Invites all allow images to be added to a text. Texts that include an image are sent with the MMS protocol which is more advanced than the SMS protocol as it allows for image attachments. Sending a text with an image will require more credits than a text without an image. Each image adds two credits to the "cost" of a text message. When an image is included in a text an option for the position of the image is shown. The default format for MMS messages is for the image to be sent first with the text to follow. Should a client wish to send the text first followed by one or more images, the "Display text before image" option can be chosen. When choosing this option an additional credit is applied to the cost of the text due the the fact that this will require the sending of two seperate texts to create this text-to-image order.
