Fix jpeg returning None for image_height_width_channels (#3885)

### What

Small mistake (maybe merge error) that slipped into #3541 


before:

(actually curious it says depth 4 here; that must be a bug on the
logging side though. Same behavior [as
before](https://demo.rerun.io/pr/3838/examples/structure_from_motion/)!)
