I think you probably need to install triangular wheels in readiness, because they are best for getting up stairs.
All pictures are missing, but its nothing wrong with what you are doing. All pictures are missing from everybody's recent posts.
The one exception is Stephan's picture in http://community.coreldraw.com/forums/t/32774.aspx because he has hosted the picture on his own site and used the HTML img src="...................." to display the image straight from there.
It looks like there's a fault with the forum server or software -- or that somebody has accidentally reconfigured it to disable image upload. Though I'd expect the upload option not to be offered in that case.
