1-In the image , where there is region that is denoted by black line, lines have curvature .when you zoom on that region lines are strait.

How can I make those lines seems strait?(while low zoom)

2-Which logo do you suggest for this cover from this link:

http://php.net/download-logos.php

3-What is your idea that covers where the lines start by light? ( like a moon that lights to lock)

4-About the logo in left corner,I want put this logo on spine. But he problem is that “security” will hide, Because it will become very small. What can I do for that?

Thanks in advance!

Sorry but I refuse to wait 50 seconds to view an image - not your fault, mega upload just sucks.
Could you use a different free upload service next time?!

As you see . lines in region surrounded by more gross black line, are more strait than line surrounded by other black line in top.

This is Illustrator file :

which one is better this link or the past one?( of the lines)

I have no real solution, but the only thing I can think of is that the curvature you are seeing is probably just caused by all the lines starting to converge (coming together) in that area.

2-Which logo do you suggest for this cover from this link:

If you are planning on having that cover printed, then the top logo is the only one you should use. The rest of the images are too small…meant to be used for the web or screen. The top logo has EPS and Illustrator format files available…suitable for printing.

3-What is your idea that covers where the lines start by light? ( like a moon that lights to lock)

I have no advice or help to give except to say that it sounds like an interesting idea.

4-About the logo in left corner,I want put this logo on spine. But he problem is that “security” will hide, Because it will become very small. What can I do for that?

One option would be to place the text “Security” on the side of the PHP logo instead of the bottom when placed on the spine.
