Some of the Captcha Pictures are Really Unclear

This is minor issue, but some of the captcha pictures when logging in are really hard to determine.

Select all images with a storefront: A bunch of random buildings, some are obviously store fronts, the others are extremely unclear. A very large building that looked like it may be a museum/office building was counted as a storefront. A building that looked very much like a store with words written in another language was not counted as a store front.

Select All Cars On one instance, a bus was counted as a car, on another instance it was not counted as a car Same thing happened with Limo and truck pictures

Select All Images with Food A bowl of random unlabeled material/goop was not counted as food, it could have been cosmetics or something but from the picture it was clearly possible that it was food, but not easily determined.

Most of the time I can login with only 1 attempt, but there have been a few rare cases where I had to do it more than 5 times to login
