Hi ciscolara, you can't load external reflection textures in Lumion.
Lumion uses a single 360 degree panoramic reflection texture which is projected onto all reflective materials. If you want to change the 360 degree panoramic reflection texture, you'll have to add the Reflection Control object in the Lights -> Utilities category to your scene, and move it around until you're happy with the reflections. A position near the camera often works well.
