Learning with images or without?
Do you learn flashcards with or without images(and why)? I always put them off because sometimes you don't really know what the image explain and than you combine a spanish word with a strange image. A sentence is very clear what it means so you can not get confused. There are exception like colors then an image is obvious than a word.
I like my flashcards without images, unless, like you say, it's a very clear connection to the word.
For example, a picture of an elephant, an eye, the color red....all of those would be fine on flashcards.
I make flashcards each week (from index cards), which have new vocabulary that I learned during the week. I keep them by my bed and review them before I go to sleep.
