Q:

Copy only images in a specific directory ignoring the sub-directories in it

Excuse me for my Bad english.I want to copy only images(.png) present inside a specific directory(serenity) ignoring the sub-directories(datatables, images..etc,) in that, to another directory.
  find /home/user/Selenium_new/Staf/target/site/serenity/ -iname "*.png"

I used the above command to get all the images present inside the serenity directory, but it is also fetching images for sub-directories as well.The result of the command is:
/home/user/Selenium_new/Staf/target/site/serenity/images/success.png

Question2: How to copy only those above images(directory Images) to another directory (/home/user/temp)?

A:

Why even use find?
cp /path/to/dir/*.png /path/to/secondDir/

Copies all png images from the first to the second dir.

A:

If you want to use find for whatever reason and not the cp then you have to use -maxdepth option with 1:
find /path/to/directory -type f -maxdepth 1 -iname "*.png"

It only look to the directory specified and not the sub directories.
To copy:
find /path/to/directory -type f -maxdepth 1 -iname "*.png" -exec cp {} /home/user/temp \;

-maxdepth levels
  Descend at most levels (a non-negative integer) levels of directories below the
                starting-points.
