Two things to check:

1) download your image from the web site (right-click, save image...) 
and compare it with the one you uploaded: same type (not a PNG turned 
into a JPG...)? same file size (otherwise it has been recompressed), 
same image size?

2)  check that the image in the web page is exactly the size you set in 
Gimp (make a screen shot, import in Gimp, and put your original on it as 
a new layer and see of they can be made to overlap exactly). If the 
image is set to a different size by HTML directives, your browser will 
rescale it on the fly and this may not be pretty.
