Hey yes i got link to add photos in GCkey with the specification same as you mentioned earlier like:
Frame size
- The final frame size of the photo must be at least 35mm x 45mm.
- The photographs must show a full front view of the head and tops of shoulders, with the face in the middle of the photograph.
- The size of the head, from chin to crown, must be between 31mm and 36mm.
- Digital dimensions are often expressed in pixels or DPI (dots per inch). The physical dimensions in pixels must be at least 420 x 540.
Quality/resolution
If an existing photo is being scanned, the minimum resolution must be 600 pixels per inch.
File format
- The file may be submitted in JPEG or JPEG2000 format.
- The final size of the image should ideally be 240 kB (kilobytes), but not less than 60 kB.
- The image must be in colour (24 bits per pixel) in RGB colour space, which is the common output for most digital cameras.
So to verify this when i spoke with agent, she told me to follow the link in request letter which says the photos must be of 50mm X 70MM size. and she don't have any idea about format like jpeg, pdf to zip file i can use since i need to submit photos front & back(with info of studio and PA details). there is only 1 upload tab for photos.
I am looking forward to help on this as i am really confused at this point. i am thinking to submit schedule A via GCkey and mail they photos with size of 50 X 70.
