Please don't be sorry to ask. That is exactly what this community is for. When I first joined only about 3 years ago, people helped me a lot. When you gain this knowledge, and you know the answers to questions, it feels good to help others.
The only time I uploaded just images was this
https://www.planetminecraft.com/project/first-adventure-map-work-in-progress/
That is modded Java, but the principle is the same.
Step 1, get some great screenshots.
Find a great location
Make sure you are in 1st Person (looking through the player's eyes)
Hide your character's arm and HUD (Windows press F1)
Adjust what's called the field of view (FOV) within the video settings. Mixing it up with some Wide-angle and some Telephoto (zoomed-in) shots will look great.
Take the shot
'For the Windows 10 version of Bedrock Edition, press ⊞ Win + G to open the game settings overlay. Under Game Capturing, click the camera button to take a screenshot. A notification then appears showing where the screenshot was saved. The default screenshot save folder is
C:\Users\<username>\Videos\Captures'
Repeat until you have enough photos
Step 2
Go to your profile icon on the top bar in Planet Minecraft
Go to 'Content'
Click the CREATE NEW button
Click MAP, then follow the options.
If you add photos, you should be able to publish without uploading a map.
