Yes, they are.
My brother offered to fix a picture for me using photo-shop. I say:
After looking at the photo, I think I can/could just fix it myself.
Are both okay here?
Why is could okay here as well?
Shouldn't it be just can because could is a possibility and photo shop is something we all can use.
I said If can or could both are ok for this sentence,so my question is
What's the difference between can or could?
