The first two things to do:

1) check that the version exported on your PC is OK (open it in 
Firefox/Chrome with File>Open
2) Download the image again from the web site (right-click and "Save 
image", usually) and compare the two files (as a first shot, the file 
sizes). If they aren't identicaml, then the web site is post-processing 
your image.

If you export as GIF, remember that there are only 256 colors in a GIF. 
If you work in RGB mode, you won't be made aware of this limitation in 
Gimp, and you will discover it when looking at the exported image. So to 
avoid surprises, if you intend to export as GIF, use Image>Mode>Indexed, 
as least just before exporting, to have an idea of what you image will 
really look like as a GIF.
