How long will a picked ripe tomato last?

I went out to my garden and had to pick many ripe tomatoes before I was ready for canning. In fact, I hadn't planned to can until another 4 or 5 days. My question is this...will the ripe ones I picked keep another 4 or 5 days? Is there anything I can do with them to help them stay for a certain length of time?
thanks!
