Your jpeg needs to be a max of 512 x 512 pixels. In the project window, right click 'Materials' and select 'Add new material' Double click the image field on the right hand side and browse to select the jpeg file. To make it a texture for walls or ground, click and drag the material onto the object in a cad view. Note: I believe its only possible to add materials to 'Forms' in the Objects library, and not for example the pre-built Stages for example.. HTH, Paul
