Json key has '#'

Currently I need the URL for an image and im getting it through the JSON file. Im not sure to acquire the key that has the URL due to the key having a '#' at the start. Here is the JSON:

{  
     "#text":"http://ift.tt/2hIgA77",
     "size":"small"
},
{  
     "#text":"http://ift.tt/2AbhC2C",
     "size":"medium"
}
