Lock function for images/objects?

[Calybos1]

I'm trying to add, copy, and rearrange a number of text and graphic elements on a page that has a large background image (filling the entire page), and I keep accidentally selecting and dragging the background image by mistake. It's not possible to draw a selection box around anything without clicking the background image.

Acrobat doesn't seem to have a way to "lock" the background in place so it can't be dragged or deleted. Any suggestions?

Don't do it in Acrobat... It was not meant to be this type of editor, and PDF files were not meant to be edited like it, so doing so will always be tricky and often very frustrating. Go back to the original file used to create the PDF, make the changes there and then create a new PDF file from it.

a thing i found after having this same issue. im not trying to reinvent the wheel with my document, i just want to lock the bg image which is not a high ask of any adobe product. I went into Edit PDF, open Layers (which is useless mind you) and "import as layer" my image, which then creates a layer with just that image i can hide or go into and lock. but why that process is so strenious? well never know. 

once i finished this i realized IT DOESNT LOCK A SINGLE THING ON THE PAGE WHAT A USELESS APP
Also theyll let you create a layer in acrobat but i cant delete one hahaha.

Digitally sign the file and/or apply a security policy to it if you want to lock its contents.

haha appreciate you but I'm not trying to put a security policy on a pdf. All I wanted is to lock a background image from being selected and moving so I can do minor text editing like changing a time and date. But alas Illustrator conquers again.
