Lightroom query (1 Viewer)

I've just embarked on using Lightroom to catalogue and process my images and am pleased so far with the organisational improvements this is providing. I've come across something that I cannot explain though and would appreciate any advice on what might be happening.

After processing in LR and exporting into Photoshop as a jpeg, I end up with an image that I then upload to my blog. The image of the first Nightingale taken on 1st May and viewed here http://robinsbirds.blogspot.com/ looks different in terms of exposure when clicked and opened in a new window as opposed to the view in the Blog. Other images look OK when opened in a new window despite being uploaded following the same workflow.

Any ideas ? I've definitely not noticed this before.

Robin

Just had a look and doesn't look different to me...

well they are different sized images for a start ... 329*400 32KB and 986*1200 107KB ...

I'm confused as to how the image size would affect the exposure ?

And interesting that you don't seem to see what I see ?

they certainly look different, the chances are because one is a better quality image than the other (less compression artefacts, more detail); whether you could really call that a difference of exposure is moot?
I've said enough anyway, I know nuffink really

I see the same thing for the third image under May 1st, it looks more reddish brown in the small size and colder brown in large. Looking at the first image under April 21, the cast looks identical but the small size is a little blurry, as if the downsizing software have caused trouble.
