Thank you for your reply.
This is the way I am doing.
The thing is, my sequence is not starting from 0
🙂
a little bit of calculation is needed (although I have done that already).
If there is something like, when I stop at certain frame (or 1 frame before/after) of an image sequence, I can right-click and choose “Reveal this frame in Finder” will be perfect.
Maybe I should write to Adobe putting it as a request feature for image sequence.
