Testing uploading an image
Example photo.jpg
Seemed to work via the method referenced above, can you see the example tstat? Where in the process did your photo upload not work? (BTW, that is what the correct D24(T) tstat and gasket look like.)
Anyway, your gasket being only 2 years old is still probably in good enough shape for the time being as long as you did not see any gouges or other deformities in it, and it did not get soaked in oil or overheated.
