[SOLVED] Automatic resizing of the header image

Hi
What are the settings in the Layout section (for Layout WIDTH and type, Layout MIN width, Layout MAX width) in order to get the header image to automatically resize according to the browser size or screen resolution?

Take a look at http://palestine-cyprus.com/
The header width is 1284px and when the screen resolution is e,g, 1024x768, it is cropped.
However the image in the post below is resized. How can I achieve this?
I have tried a number of combination for the above value without success

Any help is greatly appreciated
Thanks

In header.php change

PHP Code:


		
			
<!-- Header -->
<td id="header" colspan="<?php echo $cols; ?>">
        
<?php bfa_header_config($bfa_ata_configure_header); ?>

PHP Code:


		
			
<!-- Header -->
<td id="header" colspan="<?php echo $cols; ?>">
<a href="<?php echo get_option('home'); ?>/"><img id="headerimage" src="http://palestine-cyprus.com/wp-content/themes/atahualpa3/images/header/palestine-cyprus.jpg" alt="<?php bloginfo('name'); ?>" /></a>
<?php # bfa_header_config($bfa_ata_configure_header); ?>

Still in header.php find

Code:

// with caption

$bfa("div.wp-caption").each(function() {

and add the following before it

Code:

// headerimage

var headerwidth = $bfa("td#header").width(); 

$bfa("#headerimage").each(function() { 

var maxwidth = headerwidth + 'px';

var imgwidth = $bfa(this).width(); 

var imgheight = $bfa(this).height(); 

var newimgheight = (headerwidth / imgwidth * imgheight) + 'px';    

if (imgwidth > headerwidth) { 

   $bfa(this).css({width: maxwidth}); 

   $bfa(this).css({height: newimgheight}); 

}

});

And at HTML/CSS Inserts -> CSS Inserts put

HTML Code:

img#headerimage{

max-width: 100%;

width: auto 100%;

}

img[id~=headerimage] { 

height: auto; /* hiding from IE6 */

}

Thank you very much Flynn
That did the trick. However, all the code changes are in header.php (and not index.php)

I would definitely not managed alone
Thanks for the support

Sorry about that, I changed it in the post above, the Javascript was also slightly wrong, it's not working in IE6 and throwing an error in IE7, it's corrected now in the post above. In header.php it should look like this now:

Code:

     // without caption

    $bfa(".post img").each(function() { 

        var maxwidth = centerwidth - 10 + 'px';

        var imgwidth = $bfa(this).width(); 

        var imgheight = $bfa(this).height(); 

        var newimgheight = (centerwidth / imgwidth * imgheight) + 'px';    

        if (imgwidth > centerwidth) { 

            $bfa(this).css({width: maxwidth}); 

            $bfa(this).css({height: newimgheight}); 

        }

    });

    // headerimage

    var headerwidth = $bfa("td#header").width(); 

    $bfa("#headerimage").each(function() { 

       var maxwidth = headerwidth + 'px';

       var imgwidth = $bfa(this).width(); 

       var imgheight = $bfa(this).height(); 

       var newimgheight = (headerwidth / imgwidth * imgheight) + 'px';    

       if (imgwidth > headerwidth) { 

       $bfa(this).css({width: maxwidth}); 

       $bfa(this).css({height: newimgheight}); 

       }

    });

    // with caption

Great Flynn thanks!
I edited the code for IE as well

Hey Flynn,

"And at HTML/CSS Inserts -> CSS Inserts put"

You had me right up to this point.

I've been wading through this slowly and (I hope) carefully, but this instruction threw me for a loop.
Where or what is "HTML/CSS Inserts" ?

Your help is deeply appreciated. I'd love to get my header resizing automatically....

Bill

Flynn

It's at Wordpress Site Admin -> Appearance -> Atahualpa Theme Options -> HTML/CSS Inserts -> CSS Inserts

Wow.
I didn't expect - and probably don't deserve - such fast service.
That did the trick for me - it's working great - although the blog is still only half built.
Many thanks and I hope to learn enough here to repay the favour - or at least pay it forward.

Oh. I spoke too soon.
My header image is resizing, but now all my categories, pages and logo section have disappeared. The change to Header.php must have over written code for those items. I'll wade back in there to see if I can figure it out. If anyone has any ideas though, I'd appreciate them...

Hey Flynn, does this step hold true my version as well (3.32 I think)?

I can't seem to find that code.

Should be line 738 in header.php

Great forum for this theme. Time to donate.

In the meantime, I'm not a programmer, don't know much about .php but nevertheless I need to fix my header since my webmaster is as responsive as I'd like.

How do I get at the php code to change it? Is it through the Theme Options in WP or do I need to go to my cPanel? If it's cPanel, how do I get to the code?

Thx.

Flynn

header.php is in the theme's main directory

When uploaded it is at /wp-content/themes/[theme-name]/header.php

[theme-name] can be atahualpa, atahualpa3, atahualpa332 or similar

You'd edit header.php with a text editor such as Notepad or Notepadd++ and upload the edited version of header.php with a FTP Client software such as Filezilla to your web hosting account and overwrite the existing /wp-content/themes/[theme-name]/header.php

Thx again.

I don't know CPanel well enough and currently don't use it but it's entirely possible that you can edit this way right on the web server in CPanel, without the need to re-upload a file that you modified on your desktop computer.

Hello Flynn

How close is the above information able to assist me in making sure my site fits on all monitors (without needing to scroll from the left to the right.) - I had been informed I needed to change something from pixels to percentage. Hope you're doing well; Mark

Atahualpa already fits into various screen sizes in its default state when you choose a fluid width layout. The header image gets cut off when required. The code above is about not cutting off but shrinking the header image instead

I'm still trying to re-size my header image automatically. I tried using the code above but I noticed that some of Yiorgos' code is in there too so I'm hesitant about doing just a copy 'n paste. So I'm asking questions instead of trying it out (not a programmer). Sorry.

By default, the larger headers will be cropped, correct? On the other hand, if it re-sizes automatically, does the resolution stay the same or will the header quality be affected by the re-sizing?

If the resolution stays intact, that's great.

If not, then I have to decide what the best image size would be. For example, on my widescreen laptop a 1300 pix header looks great but on my 17" desktop, it gets cropped. If I use a 970 pix header for my desktop, then it's way to small for for laptop. I guess that brings us back to auto re-sizing - as long as the quality is not affected by the re-sizing.

My WP site is at http://www.directmailinsider.com

What's the best way to go? Thanks for your help.

Rainer

P.S. You are very responsive and helpful with these posts, so it's donation time now.

Flynn

The image resolution & quality would change. The default setting is to crop the image, with the option to choose from which end the image should be cropped, at Theme Options -> Header Image -> Header Image Alignment

This worked well for me thank you VERY much!

..tut mir leid! I spoke too soon. The fluid rezizing works great, but now my top page menu is gone. :confused: oops.

What did I do wrong?

Thank you

Rainer

Apr 12, 2009 10:13 PM

Thanks, Flynn. I got my header to re-size automatically. But somewhere along the way, I lost my menu bar along the top. Can you tell me how to get it back?

Thx.

Looks like we have the same problem. See my post ABOVE.

The solution above was geared towards a site that wasn't using anything but the header image

In header.php remove the hash # character from this line again:

PHP Code:


		
			
<?php # bfa_header_config($bfa_ata_configure_header); ?>

And at Theme Options -> Header -> Configure Header Area

remove %image

Rainer

Thank you, Flynn. What we do without you?
