Faldage:

I would have liked to believe you when you said, "It's not how much coffee I drink, it's when I can get back to a computer."

Does that work? If not, okay. If so, then why not "Jean would have liked to see those pictures?"

For my dime, so far, the more complicated tense is less desireable because it requires more effort to interpret. The question is which is more accurate. And, I think, that is only *really* the question if the statement is something "more" than casual.
