1st method:
Save the ppt as html. (Click File > Save as. Select Web Page under Save as
type).
Open the output folder, and look for the picture. Replace it with a new
picture that you want, and at the same time, ensure that the filename still
remain the same.
For example, if the filename is slide0001_image001.jpg, rename the new
picture as slide0001_image001.jpg and overwrite the original picture.
Now, open PowerPoint.
Click File > Open. Open the presentation (in .htm format) and resave it as
normal presentation.
2nd Method:
You can use Animation Carbon to copy the animations from one image to
another.

Try this in the future:
Another good way is to fill an autoshape with the image instead of using
Insert > Picture. This allows you to change the image anytime you want
without losing the animations. Check this tutorial out:
