wms/wfs layers now overlapping in OpenStreetMap layer within qGIS

As stated in my title, I’ve added two layers, one WMS (URL: [http://www.patrimonioculturale-er.it/wms]1) and one WFS (URL: [http://www.patrimonioculturale-er.it/wfs]2) into my qGIS project. They work nicely displaying the complete data → [http://tinypic.com/r/23rvbs/8]7

But when I’ve then added a map using OpenStreetMap layer as described in OpenStreetMap guide, here (URL: [http://irs.gis-lab.info/]4), the other WMS/WFS layers disappeared.

Starting with all the layers hidden when I add the OSM layer along with all the other layers they don’t show up together.

My problem consists in the fact that I am not able to overlap all the data.

This is what I mean:

  1. the data the I want to show → [http://tinypic.com/r/23rvbs/8]7
  2. the OSM layer covering all the others
    layers (apart from one (?)) → [http://tinypic.com/r/33my044/8]8

How do I make a comprehensive map also showing the desired objects?

It seems to me that you are trying to overlay with a rendering of the map. I’m not aware of any rendered versions htat have an alpha channel. It sounds likely you are trying to overlay with the vector map. If and how you can do this is likely to be specific to the particular GIS tool that you are using.
