Hi Bob,
I don't know about the software on our site, what I mean is how the software handles uploads of photos, resizing them etc for example. I suspect that your photo if in a large file size would be optimizes to an acceptable file size before it is posted here.
You might like to reduce or optimize your photo image before you upload it to the site here.
The link to optimize an image is here ---->
http://www.imageoptimizer.net/Pages/Home.aspxJust follow the instructions when you open the above link it is quite easy to use and it will reduce the file size however not the size of your photo.
On our site Peter (our past President) made a good write up about posting photos, you may like to have a read of it.
Here is the link ----->

Hope this helps somewhat.
