I have a slide with number images say 1- 50 and I need to design in such a way that whenever we click on any number it should popup with new image .Can you assist on this?

"it should pop up with a new image" is ambiguous to me.
What is it? The slideshow?
What new image?

Generally you can place a blank rectangle background over images and move images to the front or back upon clicks.

I have a slide which has numbers (images) 1 -10 while clicking upon each number it should pop up with a new image.

The purpose of this slide is to celebrate an event where the team members trying to click any number then it should pop with a gift image.

If I'm right, you want an image to disappear when it is clicked on, and at the same time, a new one to appear. Attached to this message is a version of what I think you want.

I generally use office 2016, but I do have a copy of office 2007, so I will be using that for this.

First, I created 2 shapes - a circle and a square. When you click the square, it would disappear and the circle would appear.
Then in the animation tab, I selected the square and pressed custom animation.
From there I pressed Add effect -> Exit -> More effects -> Disappear -> Ok
Next, I pressed the dropdown next to the animation -> Effect Options.
In that window, I went to Timing, then clicked Triggers, selected start effect on click of, and from the dropdown, I chose Rectangle 3. (I also pressed 'ok').

Then I did the same thing for the oval, but the animation was an entrance effect (appear).

If you would like pictures, let me know - I'd be more than happy to help.
