img2json: get your image metadata via App Engine
Written by on August 12th, 2008 in Uncategorized.
The tradition of placing small, useful services on App Engine continues. This time, Adam Burmister has created img2json, a Google AppEngine service that extracts metadata from image URLs.
The metadata can be as simple as width, height, mime type, file size, but it also extract EXIF metadata (camera make, manufacturer, GPS positioning, orientation, etc).
To use the service you just need to talk back to a URL such as:
