link to larger image doesn't work when there is no caption

[mapsam]

caption length > 0 is required for all of the linking to work. Should write a quick checker in there something like if(p._caption) { ... }

required a check for the params._caption to be set to true, as well as the actual caption in instagram.data[i].caption to not equal null

if(params._caption && instagram.data[id].caption) { ... }
