By default (except for articles), Codeproject does not host your contents (image, packages) related to a message. If you need to add some images, you could use some free image-hosters like http://imageshack.us/
Just add the file to a free web-hosting-service (or like imageshack, a image-hosting-service) and reference the image using the full URL to the online-content.
For example: http://imageshack.us/photo/my-images/831/bloominbusinesscard.jpg/
Hope this helps.
Best regards and happy coding,
