Hi diogodasilva ,
Which version of panoweaver do you use ? Do you use professional verison Panoweaver7.4 ?
I wonder if your question is you want add a link to your web in the panoVR by add a hotspot button?
When you add a hot spot in your stitched panorama ,except "popimage" " text" "hint" you will see " link to URL" ,so you can click it and do some settings .You can add images or button shape hotspot as well.
If i misunderstand your question,please let me know.you can send email to Support@easypano.com
