You promised that you would post a photo.
Then you said that you did post a photo.
Then you said it mysteriously disappeared.
Then you said you'd try again.
Then you said you were too busy.
Then you said that your photo was too fuzzy.
Now you are saying that you need people to be understanding as to why you can't post a photo.
That's totally fine if you don't want to post a photo - but you shouldn't have led people down the garden path with the odd excuses in the first place. You should have said in the beginning that you didn't want to put a photo up. Say what you mean, mean what you say, don't promise things you can't deliver. How can people believe you if you fudge things?
