WHERE I find Jquery Image slider

This answer might be obvious, but... Try Google[^].
It gives me A LOT of results. I'm sure there's something there that can help you, such as this[^] or this[^] or this[^]...
I haven't tried any of them and in fact I never used jQuery. So I hope this is what you're looking for.
If you want to make something on your own Google for something like 'How to make jQuery image slider' and you'll get a lot of results as well.
Hope it helps and good luck :)
