At the moment, you can only add pictures and sounds to flashcards using our website, not our mobile app. We hope to add mobile image uploading very soon!
To add images to your flashcards using the Brainscape website, you will first want to make sure you have transformed your Deck into an Advanced Deck.
This option is available at the top of the regular Edit screen for any Deck. Then once you are in the Advanced Editor, you can simply click the Add Image option, and you will be given a prompt to upload an image file from your computer. We currently accept .png, .gif, and .jpg files. (This includes animated gifs!)
Wherever possible, you should upload the largest possible version of your image file (2160 pixels in at least one of the two dimensions. Also square images work better than rectangles), and Brainscape's software will scale it down to each device where you may be studying it. Your image will always appear below the text on your flashcard, scaled to the maximum width of the card (and whatever height that would entail).
