Ive narrowed down to this method but i don't understand why its locking the file. I believe you could use something like
using( something)
{
//do stuff here
}
But im not sure that would A) solve the issue or B) be the correct way if it did.
any ideas?

imgInFile.Save(SaveFile, ImageFormat.Bmp);
SystemParametersInfo(SPI_SETDESKWALLPAPER, 3, SaveFile, SPIF_UPDATEINIFILE | SPIF_SENDWININICHANGE);

Updated code
private void SetWallpaper(string path)
{

{

try

SystemParametersInfo(SPI_SETDESKWALLPAPER, 3, SaveFile, SPIF_UPDATEINIFILE | SPIF_SENDWININICHANGE);
}
catch
{
MessageBox.Show("error in setting the wallpaper");
}
finally
{
imgInFile.Dispose();
}
}
}
