In pfsense CP portal settings , live preview your
Page left click in Firefox or chrome to view
Your source code and make sure it’s
Something like captiveportal-image.jpg
And not image.jpg or

[alexssi]

It is well named. Firefox tells "Can't load the image".

[jaspras]

Yes the file is there.

Two more tests :
Enter console, option 8 :

ls -al /var/db/cpelements

You saw your uploaded file(s) ?

ls -al /usr/local/captiveportal

You saw the links to your uploaded file(s) ?

[alexssi]

ls -al /var/db/cpelements
-rw-r--r--   1 root  wheel  39268 Apr  9 14:40 captiveportal-logo.png

ls -al /usr/local/captiveportal
lrwxr-xr-x   1 root  wheel     52 Apr  9 12:48 captiveportal-logo.png -> /var/db/cpelements/captiveportal-logo.png

Next test :

This one :
@alexssi:

It is well named. Firefox tells "Can't load the image".

this isn't something you post on a forum like forum.pfsense.org. We are not end-users here, but firewall admins  ;) so we have the power (to show more details).
Your browser supports a way to inspect the page it loaded, so you can see what is the URL that present in the html login page.

What is this URL ?

Btw :
When I use this

When I try http://<ip>:8002/captiveportal-logo.png. I fall on the portal.</ip>

on my setup with an existing image (an uploaded png file) I can see that image in my browser.

[alexssi]

No matter what URL I type, I always come across the captive portal page.

@alexssi:

No matter what URL I type, I always come across the captive portal page.

This is normal of course.
Any "http" access - when not authenticated - will be redirected to the captive portal login page : /usr/local/captiveportal/index.php - this is how the captive portal works.
But the "captiveportal-." are an exception.

Do you use http login or https login ?
Show us the correspond nginx setup files in /var/etc/ (not the names, what's in it).

These are mine :

[2.4.3-RELEASE][admin@pfsense.brit-hotel-fumel.net]/var/etc: ls -al nginx-*-CaptivePortal*.conf
-rw-r--r--  1 root  wheel  2596 Apr 10 11:17 nginx-cpzone1-CaptivePortal-SSL.conf
-rw-r--r--  1 root  wheel  2107 Apr 10 11:17 nginx-cpzone1-CaptivePortal.conf

What is your captive portal IP (IP of the NIC used by pfSense)
What is the hostname of pfSense and domain (System => General Setup) ?
