AP Photo Requirement - Digital Photo

[Kinku]

Hi Gurus ,

I applied for AP renewal but I am little bit confused about photos.

in the instructions below there is a note saying Digital Photos not accepted .

I clicked my photos at costco . Today I checked with costco guy and asked them are they digital . He said they are digital ...

I am bit confused now . Do I need to take one more set of photos some where else like portraid ...???

Please let me know what your experiences are ..

Thanks,
Kinku
