A little guidance please.
Being new in the forum I posted this in the new guy group.
I left the text below because it make things a little clearer.
What I want is to make newsletters available for users on my website on my server. I would like to make available what ever format they need.
I now how to convert from one format to another.
What I don't know is how to code the download to get all the pieces of the ebook. Meaning the cover picture, heading and the ePub file in one download with out using a Zipped file.
Is there a program or code to do this. Say PHP, script, program to run on my Linux server?
Can You help?

====================More Details ===========================
I want to publish newsletters from my web site for people to read or download for free if they want. Right now they are "PDF" files and Calibre converts them very easy to "epub" files.

Calibre will convert and upload the PDF files directly to my Nook Color (NC) while I am plugged into my PC and they have the cover and heading. That is fine for me but what about for others.

I see when a file is a few files. I know how to code HTML for a user to down load one files but I am not sure how to do it for the eBooks the need multiple files.

I know with a PDF file it is just a simple thing to open it and save it. That is fine for me but me but the look better in the eBook formats I have viewed.

This may be off topic for an intro group but it is what I am working.
Since I retired I keep dreaming to projects that could be done because I have more time than money.

So I want to have free newsletters or whatever in a format for the eReader that anyone could click on and download in to their device that is very easier for the user.
So can you tell me where to go? ...Wait maybe a link to more information would be nice.
