I agree with Untold. It is easier to be able to match pictures with meanings. Its a way that helps people to learn and associate the cards with their 78 seperate detailed meanings.
To just memorize the 78 meanings without connecting it to the image of the card would make it very frustrating unless you have a superior memory. But most are visual learners, and relating to the images gives each card a personality. And to me, my 78 cards are 78 parts of a story. When I do a reading, each one gives the story of whatever I'm reading on.
I've had the same deck for over ten years, and honestly, I could stand to switch to another deck. I've connected the meanings to the pictures, not the names of the cards. I'm terrible with names in normal everyday life because I am very visual, and the tarot is no different for me.
In fact, I tell my five year old daughter stories with my tarot by shuffling them and dealing them out one by one. She calls them my "story cards". Little does she know, she's slowly learning the tarot herself by connecting personalities and events to certain cards. But if I began a story with different style of tarot, she would have no idea what the cards meant.
