But I am getting a very small image, which needs to be enlarged a lot thereby losing a lot of quality, is there a way that i can specify the picture quality as well in the request
Response is like this

}

Use the thumbnails field and look for the object with is_preferred set to true. picture doesn't respond to modifiers.
