Powershell check file type

Question

I am working on a script that modifies images in a folder, for the most part, it is done I use Get-ChildItem with the directory.

So what I am currently doing is making a variable called

$fileExtension = [IO.Path]::GetExtension($files[$counter].Name)

with an if statement that is like:

if($fileExtension -eq '.png' or
    $fileExtensiono -eq '.jpg'. . . )

Is there a better way of doing this? I really want it to execute this function that modifies images if the file is an image, a folder could contain other items such as a zip which will crash the script if it picks up on it.

Now I did find an issue doing it that way, the thing that I am doing to these images is adding a number to the image itself. So Where I am doing Get-ChildItem I think I need it to just give me images. So I found that by using -Recusive and -Include @("*.png", etc.) works but if the folder has sub folders it crashes the script. How to I use the Get-ChildItem to just focus on the current directory only. Excluding Recursive the Include does not work. — l3l00

I'd restrict to desired extensions firsthand when doing the Get-ChildItem *|Where-Object Extension -in '.png','.jpg' or Get-ChildItem * -include '*.png','*.jpg' — user6811411

@LotPings - That was it! Where-Object was the solution ^-^ So if it has a file type other than common image file types it doesn't list them at all which allows the count to stay correct. Thank you so much! — l3l00
