What does Janice’s line in the fifth episode of Friends mean?

I don’t know the context, but the normal translation is:

I got the photo print back before they snapped it, you know, the one with the little vegetables . Anyway, they were really inferior, so I gave up my full-day plan and went shopping...

My understanding is: Janice went to print the photos, and then regretted it when she printed them. I thought those photos were terrible, so I snatched the negatives and prints together and went shopping.
