refactor: improve image src update

[adonyssantos]

It's not recommended to use document when you are using React.

Where do you have this issue?

• src/pages/PostForm.js
• Check if it is in other files

As an alternative

You can create a state using useState to save the image metadata, such as src or alt, and update the data using the setter.

Example

setImagePreview(prev => { ...prev, url: imageUrl });

You just have to use that state in the src of the image, like this:

<img src={imagePreview.src} alt={imagePreview.alt} />

There are more alternatives that I invite you to investigate and use the one you consider most convenient.
