Photobucket works great for fairly large pictures upto 1024 x 768 and its free. Just take your pictures and tranfer them to your PC/laptop, save them as a .jpeg file, then after signing upto photobucket upload the pictures. It allows you to specify a maximum size/resolution so you can either post normal sized pictures directly onto the forums (copy and paste image code which is below pictures), or you can post a link to a much large picture in your photobucket album. Piece of cake really.
