R grep: is there an AND operator?

Suppose I have the following data frame:

User.Id    Tags
34234      imageUploaded,people.jpg,more,comma,separated,stuff
34234      imageUploaded
12345      people.jpg

How might I use grep (or some other tool) to only grab rows that include both "imageUploaded" and "people"? In other words, how might I create a subset that includes just the rows with the strings "imageUploaded" AND "people.jpg", regardless of order.

I have tried:

data.people<-data[grep("imageUploaded|people.jpg",results$Tags),]
data.people<-data[grep("imageUploaded?=people.jpg",results$Tags),]

Is there an AND operator? Or perhaps another way to get the intended result?
