RandomImage | An Api that can get random pictures , built with SpringBoot | Application Framework library

I have a pretty simple Django project based on the one from the tutorial that I am slowly morphing into my own app. It was working fine locally. I tried to deploy it to Heroku, so I made a few changes, but it was still working fine locally (I am still working on getting it to work on Heroku). But then I ran it once more and out of nowhere I am getting this error:

I need help with my project. I am new to coding but am learning very quick. I have a random image generator but every time I click the button I want the images previously generated to be replaced with the new ones. right now the generator just adds two more images every time I click the button. My goal is that every time I click the button two new random images appear taking the place of the two before. Thanks for the help! here is my code below but i have redacted the images because i wish to keep them private for now.i put the original puppies in place of the real images.

I have a page function that shows and hides images every 5 seconds.

Instead of these two images, I need to open random images from the list each time.

I added an array with images, tried to add the creation of an image in the popup() function, and the removal of the hidePopup() function, but nothing happened.

I am trying to render a component when certain states are triggered that are passed through Context API but after adding a console.log everywhere I noticed that the problem was with my useEffect() not being run and I don't know why:

I have an array that holds countries. I need to figure out how to take three values from the array, and the 4th value needs to be the right answer.**

The answer choices (as radio buttons) need to be random and not repeated, but also contain the right answer and place it at a random location.

I'm writing function in C# which can draw random data to bitmap image. Actually it looks work but its image is looks has gradation effect and tried to disable this but couldn't make it.

What I want to draw is 'A' but I got 'B'.

'A'

'B'

How can I draw image like a 'A', not 'B'?

Below is my code...

I have a simple function that creates an image and the src is a random image from splash, but every time i call the function it generates the same image, why and how to fix it

I am trying to create an object and for it to have a shape (an ellipse), an image, and a function that somehow fills the shape with a pre-loaded image.

I already found this post, but I can't get it to work if I try to make it neat and fit it all into an object.

To be clear, this is what it would look like:

**When i try at local route is working but why not working on product ? i get 404 not found error. **
