IMGGETTER has default mimetype set to "image/*" -- may need to be settable.
attempting base64 encoding of image/jpeg responseText.   image/jpeg crammed-in to responseText may be munged, b/c inherent nature of XHR call.
referencing minified jquery.
setting up test of retreiving remote images.
gallery feature fades in.
added main photos' widths and heights, to returns JSON object.
added correct image with & height display
optimized seaching...
refactoring...
normalized data in assetconfig, changed into array of objectes, where the key is now in a property called 'type.'   Still seems to work, b/c now, the array index is used as a key.
embederator handles new data format (services as an array); uses "type" as key.
successfully translating xhr'd images (and local blobs) into *either* new blobs or base64-encoded strings.  ...will only work in browsers that support Blob and Filreader APIs.  however, need to cleanup/refactor code for readability.
file upload > blob > data:base64 string  >>>> kind of working.  needs serious refactoring, though.
