List all available sizes for thumbnails
:class:`thumb/[itemId]/[xSize]x[ySize]/ <api2.handlers.ImgThumbHandler>`
:func:`GET <api2.handlers.ImgThumbHandler.read>`
Returns the url to a thumbnail for [itemId] of size[xSize]x[ySize].
E.g. thumb/1/64x64/ returns the path to an image for the first item
and a dimension of 64x64. If the size is not available an error
is raised.
