Hi Lisa,
I’m not sure, it’s hard to debug without more details. Since the error message is complaining about encoding, I would suggest to look for the error in your image paths;
For best compatibility, always make sure to have no special characters in your filenames and paths, so no accents (u’\xe9’ from the error message is the e with accent egout) and if possible even no spaces (it’s good practice to replace all spaces with underscores in filenames).
I’m not sure if that’s the source of your problem, though, but that’s my educated guess
