Write a few sentences in English and/or Spanish when you "just" post an image. That way people can understand what this is all about.
Always use FIVE tags for all your posts. That way it will be easier to find your posts. If you write in Spanish use the tag #spanish and #espanol. That way more Spanish speaking people will find your post.
Try to use a photo editor on your phone and put a nice filter over your images before you post them. That will make them look more intersting.
