Nice shot Mark.
If you want to load a bigger image to IIS try this. Its quick, simple and does a pretty good job:
Have image open in PS
Go:
Image>Image Size. Set the width to around 900-1000>Ok
File>save as> Name file and set directory and file type as Jpeg> Save >Jpeg Options: adjust slider to get total size at the right below 200kb.>Ok
You really only need about 850 pixels in image width to fill the screen in IIS but a bit bigger gives some room to move around and not sacrifice too much detail for compression. It works very well. If you want to upload a bigger image, say 1200 pixels then just adjust the slider to the size you want.
When you are in the Jpeg Options box you can check the changes by clicking the preview tick off and on. BTW this is all with CS3
