Page Layout ⇒ I set the margins to 1, 0.5, 0.5, 0.5 in preamble but they are alternating

[John_FTex]

My margins alternate page by page - between indented and not indented. It's exactly alternating but I have no idea why it does this?

What is wrong?

For the most part, I can tell that my images and most text DO fit within the margins because if I usepackage{showframe} everything looks correct.

I just don't know why if I page through the document, it keeps alternating between left-aligned and indented.

I guess I'll turn showframe back on and see if it aligns correctly and doesn't alternate. Is it just the viewer of the document acting up?

I now realize that it has to do with the margins and the document page size I'm using, but I don't know how to fix this?

I believe someone else had this problem too.

I now realize that it must be because a book has a left and a right page. So when I went 1, 0.5, 0.5. 0.5, it alternates left and right. But I really want the right-side of the left-page to be 1" for the binding to have some room and I want the left-side of the right page to have 1".

I had just wanted there to be room to glue the pages in place but maybe I went too far with that.

Should I do this maybe?
\usepackage[
top= 0.5in,
bottom=0.5in,
left=0.5in,
right=0.5in,
bindingoffset=0.25in,
heightrounded,
]{geometry}

I want the book to be roughly 8 1/2 x 11 because many of my photos are 6" wide and that leaves some nice extra space around the photos so that the photos are INSIDE of the margins a little bit.

Update:
The above tweak of the usepackage with bindingoffset did NOT help any, it still alternates.

Does Texworks have a viewer that allows visualizing the document side by side? But I also now realize that if it's going to be a book, how will I have two versions? One for simply browsing as a pdf file and one for the publishing of the book? Hmm.

The following solved the problem for now, it no longer alternates - I can have two versions of my latex document, one for the pdf to be viewed and one for the book to be bound:

\documentclass[a4paper, 11pt, oneside]{book}

Now the pages don't alternate anymore - the margins are always the same and it looks fine.
