iOS compatible making pictures

Can you create picture based flashcards using just the mobile app? If not Im screwed as my MacBook wont support the current version of the appropriate anki app?

It is possible to paste images into fields, but not possible to create image occlusion cards. That said, your Macbook is probably capable of running Anki 2.1.35-alternate, which is still available for download, and still compatible with AnkiMobile.
