1. A method of selecting medical images of an image series for transfer, the method comprising: by a computing device executing software, performing operations comprising: accessing a plurality of transfer criteria associated with a first computing device, the plurality of transfer criteria including: first transfer criteria associated with a first value of an image series attribute, wherein the first transfer criteria indicate a first maximum image slice thickness, and second transfer criteria associated with a second value of the image series attribute, wherein the second transfer criteria indicate a second maximum image slice thickness that is different from the first maximum image slice thickness; receiving a first request to access a first image series having the first value of the image series attribute; applying the first transfer criteria to the first image series by: selecting a group of medical images of the first image series, wherein each medical image of the group of medical images of the first image series has an image slice thickness less than the first maximum image slice thickness; and initiating transfer of the group of medical images of the first image series to the first computing device, wherein medical images of the first image series that are not in the group of medical images of the first image series are not transferred to the first computing device; receiving a second request to access a second image series having the second value of the image series attribute; and applying the second transfer criteria to the second image series by: selecting a group of medical images of the second image series, wherein each medical image of the group of medical images of the second image series has an image slice thickness less than the second maximum image slice thickness; and initiating transfer of the group of medical images of the second image series to the first computing device, wherein medical images of the second image series that are not in the group of medical images of the second image series are not transferred to the first computing device.
