From Google I have gathered there are several ways for pronounce Israel, I have pronounced it is-rye-el. From googling it some seem to indicate it acceptable and another says it is vulgar and should be avoided, so I come to you, which one is it, as it seems it is used often enough...
Edit: Adding links to the links I looked at before asking and referenced above.
