Since the server endpoint expects a datafile and not an array, I tried saving images (f.png) in the working directory and then sending those images data files to the server. I am trying this way since I do not konw how to change the bytes in a _io.BufferedReader on the fly (at least yet). However when saving the original image (without any modifications) and sending the new data file to the server, the output is : I think you tampered with this report card.
\nMy question is: for this challenge, do we need to change bytes from the original image or the method I described above could in theory work (and I am doing something wrong somewhere) ?

\nModifying the image and saving it is totally fine
\nThe \"tampering message\" just means, that your faked 'A' isn't believable enough.
\nTherefore you have to create a more realistic one.
Thank you for your answer.
\nI just found it weird that feeding the original image from a different source yielded a different output message.
Exactly , i loaded the image , saved the same image again and uploaded it as a file and got the message I think you tampered with this report card. . But when i do it as per the template , i get a different message - **There's no way you're going to homecoming with those grades. ** . That got me thinking if saving the file isn't the way to go
