PowerShell Batch ConvertImage - powershell

Question

I am working on a PowerShell function that will convert jpg to png. I got that to work. I cannot figure out how to get it to delete the original jpg file after finishing. I have attempted to use the del and remove command but cannot delete the original file because it is still being used in the process. I have also tried to end the process but it ended the whole process when I put it within the foreach loop. Is there a way to get it to end the process so the file can be deleted and then continue through the rest of the images? Below is the code that converts but does not delete. If there is a better way to do this I would like to know were I can improve. Thank you !
function ConvertImage{
param ([string]$path)
$path=Convert-Path . #path to files
if (Test-Path $path)
{
#Load required assemblies and get object reference
[Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms") | Out-Null
foreach($file in (ls "$path\*.jpg")){
$convertfile = new-object System.Drawing.Bitmap($file.Fullname)
$newfilname = ($file.Fullname -replace '([^.]).jpg','$1') + ".png"
$convertfile.Save($newfilname, "png")
$file.Fullname
}
}
else
{
Write-Host "Path not found."
}
};ConvertImage -path $args[0]
How Do I use an integer with leading zeroes for the code below:
function ConvertImage{
param ([string]$path)
$Name = Read-Host -Prompt 'Input new name'
$Start = Read-Host -Prompt 'Input start number'
$Ext1 = Read-Host -Prompt 'Input Initial Extension'
$Ext2 = Read-Host -Prompt 'Input Ending Extension'
Write-Host "You input '$Name' and '$Start'"
Write-Host "You input '$Ext1' and '$Ext2'"
$i = "{0:D2}" -f [int]$Start
Get-ChildItem ("*.$Ext1") | %{Rename-Item $_ -NewName ("$Name"+"_"+"$i.$Ext1" -f $i++)}
Get-ChildItem ("*.$Ext2") | %{Rename-Item $_ -NewName ("$Name"+"_"+"$i.$Ext2" -f $i++)}
$path=Convert-Path . #path to files
if (Test-Path $path)
{
#Load required assemblies and get object reference
[Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms") | Out-Null
foreach($file in (ls "$path\*.$Ext1")){
$convertfile = new-object System.Drawing.Bitmap($file.Fullname)
$newfilname = ($file.Fullname -replace "([^.]).$Ext1",'$1') + (".$Ext2")
$convertfile.Save($newfilname, "$Ext2")
$file.Fullname
# Dispose file to stop using it
$convertfile.dispose()
# In brackets in the event that the filepath has a space
Remove-Item "$($file.Fullname)"
}
}
else
{
Write-Host "Path not found."
}
};ConvertImage -path $args[0]

Just do a Remove-Item at the end of your foreach.
function ConvertImage{
param ([string]$path)
$path=Convert-Path . #path to files
if (Test-Path $path)
{
#Load required assemblies and get object reference
[Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms") | Out-Null
foreach($file in (ls "$path\*.jpg")){
$convertfile = new-object System.Drawing.Bitmap($file.Fullname)
$newfilname = ($file.Fullname -replace '([^.]).jpg','$1') + ".png"
$convertfile.Save($newfilname, "png")
$file.Fullname
# Dispose file to stop using it
$convertfile.dispose()
# In brackets in the event that the filepath has a space
Remove-Item "$($file.Fullname)"
}
}
else
{
Write-Host "Path not found."
}
};ConvertImage -path $args[0]
