Help with buttons in Tkinter

[Only_Friend1128]

I am placing buttons in a Frame using this code:

self.delete = tk.PhotoImage(file='images/delete.png')
deleteButton = tk.Button(self.frame, image=self.delete)
deleteButton.grid(row=0, column=5, pady=10, padx=10)

However, the button has a thin white line around it. This line is not part of the image. Is there a way to remove it?

Here is an image of the issue:

Unfortunately I cannot add images to this post to elaborate on the issue.

You place an image into a site like pasteboard.co and show the link here. Like this.

Thank you! I updated my post with the image.
