IR images are incomplete and not in any protocol

In the db.sql3 database, there are already images from two infra-red (IR) cameras included (cam6 and cam7), but the files are used in no protocol. Additionally, the files of IR camera cam8 are not added by now.

Furthermore, none of the IR images is inside any protocol. I think, this is reasonable. However, this causes the files not being returned in the objects function.
