You are trying to get certificate number
There is no reliable way of getting to that certificate directly.
Instead I will will try to get you there in incremental steps
This is not guarenteed to work, and if it doesn't you will have to step through the entire roll,
frame by frame, looking for the certificate you want
1. Start by initially fetching image number
on roll
That will probably be too low, so if you tell me (in step 2) what certificate is on that image, I will try to get closer
2. Keep repeating this step until you get to the certificate you want
The certificate number on image is
3. Use these buttons if the above steps got you to the start or end of the roll
