PIL ImageTk equivalent in Python 3.x

Question

I'm developing an application with Tkinter that uses a database of `png` image files for icons. In order to use said images in the application, I open them using PIL's `Image.open`, run it through the `ImageTk.PhotoImage` function, then pass it to the widget constructor. The problem is, I'm trying to port my entire project over to Python 3.x, and because of PIL's lack of support for Python 3, I have no idea how to load the icons into the application. If anyone knew of a solution that would allow me to use the icons without having to convert all of them to `.gif` bitmaps, I would be very grateful!

Accepted Answer

PNG files, even with transparency, are correctly displayed in tkinter and ttk in python 3.4.1 on Linux, even though only GIF and PPM/PGM support is documented.

Above PNG image contains transparency.

```
from tkinter import *

root = Tk()

photo = PhotoImage(file="example.png")
photo_label = Label(image=photo)
photo_label.grid()             
photo_label.image = photo

text = Label(text="Text") # included to show background color
text.grid()

root.mainloop()
```

Above code renders the image correctly with transparency as seen below:
