Guice: Maybe I did not come across clear enough...
I converted bmp to jpg reduced file size to 280k
I upload and then view the screenshot later and its massive.
Go and look at some screen shots on this site and check the properties of the image once downloaded in the browser and you will see huge file sizes. I have uploaded png files also and it does the same on these. I am just suggesting reworking the sites code to repair the issue. I know new site code is coming soon. This is bogging the bandwidth hardcore if even 10 people are veiwing SS or theme images.
Good luck guys...
