You can attach them to your posts here if they are sized properly. Post using the "go advanced" button, select "manage attachments." When the window opens, browse to select the pictures, click upload, close the window when done, and post. If the pictures are too large you need to resize to an acceptable size.
Use the search function if you have questions as there are many posts on posting or attaching pictures and resizing them. If you are still having problems just ask.
