How to disable reference images projection on top of all objects when rendering (blender render)? im pretty new to blender and modelling stuff but i do have a problem here which i cant solve and didnt find anyone with the same problem (maybe its too basic).

Whenever i render my scene it looks like the reference images i used in the past are projected on top of all of my objects in the scene. Those reference images are not used anymore and i removed them from all planes and "Background Images".
Here is how it looks like:



In that image i disabled the model itself just to be sure that it has nothing to do with it and created a new cube. But the outcome is the same.
Am i missing something that obvious here?

EDIT: Here is the link to my .blend file (i know the texture in it is nothing special...xD). I hope it has everything it needs. I packed the textures which i used previously as example.
To reproduce the issue you just need to switch to rendered mode (shift+z).

You added texture to both your lamps, thus the image was projected onto the objects, which were lighted by those lamps. Image below explains how to check if you have a texture added to a lamp.
