tkinter bitmapimage "image doesn't exist"

Question

So I had it working, not sure what I changed but maybe someone else can take a peek and see where the error is.

here is the code the image is made and set to display in

def app_openfile(self, w, o, s):
    io_file = filedialog.askopenfilename()
    self.hex_data=Util.openFile(io_file)
    self.all_bin_data = Util.convertToBinary(self.hex_data)
    self.bin_data = self.all_bin_data
    ##infor bar call goes here
    self.bit_image = Util.makeImage(self.bin_data, w, o, s)
    print(self.bit_image.size)
    print(self.bit_image)
    self.photo = ImageTk.BitmapImage(self.bit_image, background='white')
    print(self.photo)
    self.binViewBox.create_image((0,0), image=self.photo, anchor=N)
    self.binViewBox.config(xscrollincrement=self.Scale,
                           yscrollincrement=self.Scale,
                           scrollregion=(0,
                                         0,
                                         math.ceil((int(w) * int(self.Scale))),
                                         math.ceil(len(self.binData)/int(w)* int(self.Scale))))

Now in the Util.makeimage bit, I have it set to show before it returns to verify it makes an image, and it does. But for some reason I haven't figured out yet, is why its now throwing this error.

_tkinter.TclError: image "pyimage11" doesn't exist

this is the return of the print statement before the exception is thrown

making image 1000 0 1

(1000, 96)

"PIL.Image.Image image mode=1 size=1000x96 at 0xE1ADD30"

pyimage11

EDIT:

this is an example what it should produce, but isn't pushed to the tkinter canvas

enter image description here

Update as of 08/14/2018

def app_openfile():
    io_file = filedialog.askopenfilename()
    h_data=Util.openFile(io_file)
    all_b_data = b_data = Util.convertToBinary(h_data)
    all_b_data = b_data = Util.convertToBinary(h_data)
    viewtest = Canvas(root, width=500, height=500,bd=0)
    bimage = Util.makeImage(b_data, 800, 0, 5)
    bimage = ImageTk.BitmapImage(bimage)
    viewtest.create_image((0,0), image=bimage)
app_openfile()
root = Tk()
root.wm_title('PyDMT')
root.resizable(width=True, height=True)
root.mainloop()

Took out the class stuff to see if that was the issue, but still throws error.

You should use PhotoImage instance as an image value. rather then using BitmapImage Also, you need to keep the reference of your image. im = Image.open(pathToImage) self.photo = ImageTk.PhotoImage(im) — jits_on_moon, Jul 14 '18 at 12:10
Using BitmapImage because its type '1', this is to help with loading the size of the image, since many are quite large, and a normal Photoimage takes a long time for it to be created. The self.image, self.photo is used to keep reference. The image is made only from memory, there isn't a photo. The program pulls from files. — CaptObvious, Jul 14 '18 at 12:20
I think this might be useful. https://stackoverflow.com/questions/20251161/tkinter-tclerror-image-pyimage3-doesnt-exist/20259317 — jits_on_moon, Jul 14 '18 at 12:21
I am finding it seems to be with the .create_image bit. Thanks for the suggestions Mr J. — CaptObvious, Jul 14 '18 at 12:41
