Hi folks,

This series of patches drop the usage of image loading in the example
`virtual.yaml` config file, as it requires images being installed / 
placed in certain paths.

The series also passed the gitlab pipeline:
https://gitlab.freedesktop.org/chenghaoyang/libcamera/-/pipelines/1238353
, with only merge-check warnings remaining.

Please check again. Thanks :)

BR,
Harvey
