imageGrid | Google Images inspired grid built for Knockout.js | Grid library

Hi I am new to react and I would like to know why my image gallery isn't updating when clicking on the date Tab. I made on purpose the fact that once you clicked on the tab, it "pops" one object of the array, but it isn't updating in real time. I can see the result only if I change the size of the window. Is there something to fix it?

galleryPage.jsx

I'm plotting an image with 4*6 grids with mpl_toolkits.axes_grid1.Imagegrid:

I'd like to know how I can implement an if statement inside .map()
See code below.
Currently the delete button is disabled if the image is not uploaded by the current user, but my goal is to not render the delete button at all.

In my react application I am trying to use context api. In my component I am importing the context but it is giving error that object can not destructure the property. I am trying to implement cart functionality in my app. I am using hooks.

I am trying to test how much information will I lose if I convert (initially) 16-bit images that I've read from .dcm files using pydicom module, to 8-bit images. Here is visualization code that I am using:

I have an image grid. Each image on tap should push a view on the NavigationView with the image details.

The navigation link works as intended, but when I press the back button it opens the next image and so on until it has cycled all the images. What is going on?

This is the View:

i made this button is dispaly :none and it will show up when the mouse move on the img-wrap, but there is a imge in this div, how to make a button on the top of other elements when the mouse move on the img or img-wrap? What is the appropriate way to solve this issue? I have tried using Z-index yet,but it did not work.

below is my js file.

this is my first react project by using firebase, everything is correct which all upload function works very well, also all images can be shown, but i use firebase.firestore.collection('image').document(doc.id).delete() when i want to delete one of the images, it shows an error which is:

Uncaught TypeError: db.document is not a function

I do not know what is going on, can someone help to resolve it, please?

projectFirestore = firebase.firestore() in the firebase config file.

This started happening suddenly when debugging a seemingly unrelated error on Netlify build. I do not have this issue locally. I've cleared my cache, deleted my package-lock and node module folder and updated everything, as well as ran a build without cache on Netlify. I've checked the file/folder names for case sensitive also. What could it be?
