Welcome to the forum
Where did you get the sketch from and which Arduino board are you using ?
@gaby8277
Welcome to the Forum! Read the forum guidelines to see how to properly ask a question and some good information on making a good post. You will get faster and better help if you post all your code as requested by the forum guidelines.
Please go back and fix your original post.
Also please describe what the hardware do you use.
im using xiao esp32s3, the sketch i used is from a video of a project im doing ,https://www.youtube.com/watch?v=gmqgAcnKeFU&t=6s
Please insert the code to the forum as text using a code tags.
The video link for code analysis is of little use
The file is in the link to the code in the video. Download it and put it in the same folder as your sketch

how i do that ?
Please follow the advice given in the link below when posting code, in particular the section entitled 'Posting code and common code problems'
Use code tags (the < CODE/ > icon above the compose window) to make it easier to read and copy for examination
https://forum.arduino.cc/t/how-to-get-the-best-out-of-this-forum
Please post your full sketch, using code tags when you do
Posting your code using code tags prevents parts of it being interpreted as HTML coding and makes it easier to copy for examination
In my experience the easiest way to tidy up the code and add the code tags is as follows
Start by tidying up your code by using Tools/Auto Format in the IDE to make it easier to read. Then use Edit/Copy for Forum and paste what was copied in a new reply. Code tags will have been added to the code to make it easy to read in the forum thus making it easier to provide help.
It is also helpful to post error messages in code tags as it makes it easier to scroll through them and copy them for examination
Which part don't you understand ?
Do what?
Are you asking how to copy a file to a sketch folder?

i chose the option «code» and it stayed like this
you inserted the code incorrectly again
i dont know how to put it corrctly
I suggest that you use the method that I suggested
Start by tidying up your code by using Tools/Auto Format in the IDE to make it easier to read. Then use Edit/Copy for Forum and paste what was copied in a new reply. Code tags will have been added to the code to make it easy to read in the forum thus making it easier to provide help.

Compilation error: camara_index.h: No such file or directory
it gives this error everytime that i verify
Did you put camara_index.h in the same folder as your sketch ?
It should show up as a tab in the IDE editor window
yes it shows up in the tab but the promblem continues
