In a spin

Really struggling for time just now and I need to investigate a problem with the Camera/Memory Card/PC/Settings.   For a few days now I've been taking a bunch of pictures while I'm out but when I download them to the PC I only have 3 or 4. 

Today I only have this ONE - but took around 40 - 50, and reviewed a few of them as I went along so I know they were there at some point.    And I have a feeling I won't be able to recover them.  

I suppose I'm lucky that at least I had one, otherwise no Blip.
