I the release post of com_resized there was asked the question why one should use com_resize. There are three reasons to use it:
- The generated images aren the size you want them to be. So they’re smaller of size than the original images.
- You won’t get any ugly resized images (see the example below).
- It works with remote images. So you can link to an image one someone else’s blog and they get resized to the size you want + cached. So that way they get loaded from your own server: so faster.
No more ugly resized images:
The one on the left is without com_resize. The one on the right is _with_ com_resize. If you don’t see any difference. Your browser is probably doing some fancy stuff with the image. In that case you don’t need com_resize. But maybe the readers of your blog do!
For the people who don’t see any difference (leave a comment with your OS + browser, please!) I have attached a screenshot. Made in IE6, so the font is ugly too

Hi Leon
Thank you for your explanations and thank you for your work but… sorry to insist. There is a copy of the phpThumb script well documented inside of your resize plugin. But no documentation how to implement any code of com_resize in wp? In your example above your using also the phpThumb code? Or is there something else..?: …wp-content/plugins/com_resize/phpthumb/phpThumb.php?src=/wp-content/uploads/2008/05/space_station.jpg&q=90&w=200″ alt=”" width=”200″/>.
Hi Roger. Thanks for all your comments :p Else my blog would be so empty
I had some nice api for phpThumb planned for the next version of com_resize (nice mod_rewrite url’s).
I don’t even know how my plugin reacts if you add some phpThumb url filter’s to the image.
Hmmm… I think you dont understand what I need….
Question:
How do I use your resize code in wp? Please make me 1 example how you integrate the IMG tag… and resize..?
%-)
That’s very simple: insert an img with a width and/or height attribute and it will be automatically resized! The original image is then replaced with a link to phpThumb.php?src= and the original image will be resized.
Ow yeah: the original image will only be resized if the image-width and the width/height in the tag-attributes are different.
When does the re-sizing occur? When you create the post/page in WP, or when the page is loaded?
One of my clients has added pics (straight from the digital camera) to a WP page (see the Efficient Recycling page on the website link above). These are the WP Thumbnail pics, but load really slowly. I’ve installed the com_resize plugin and activated it… so how do I get the images on the existing page to re-size.
Thanks (if this “does what it says on the tin” …. your plugin will be added to all my clients sites!!!)
DuncanC: they are resized when the page is loaded.
I had the same problem: one of my clients (a Ducati dealer) posted hi-res pictures on their site. That’s why I created this plugin.
All you have to do to resize the images is: add an image, add a width and/or height attribute and reload the page!
I looked at the link you posted and it took this img as an example:
http://thinkpinkskips.co.uk/wp-content/uploads/2008/05/pict0002-300×224.jpg
I think the problem is that the difference between the real width/height(300×224) and the width you want (275×210) is too small. I believe the difference should be at least 12%. But you can find that number in the sourcecode (and adjust it if you want).
Hi Leon,
I use com-resize and think it’s great.
I have WordPress installed in a /wp subdirectory.
Many of my images are in /wp/wp-content/uploads
and those work fine. But, some of my pre-Wordpress
images are in /images — those do not work.
For example, this (remote image) works:
http://transom.org/wp/wp-content/plugins/com-resize/phpthumb/phpThumb.php?src=http://www.transom.org/guests/review/200801_creature_comforts/assets/thumbnails/water_bugs_80.jpg&w=80
But, this (absolute to docroot) image does not:
http://transom.org/wp/wp-content/plugins/com-resize/phpthumb/phpThumb.php?src=/guests/review/200801_creature_comforts/assets/thumbnails/water_bugs_80.jpg&w=80
It seems that the version of phpThumbs that comes
with com-resize sets the phpThumbs ‘document_root’
to be that of the WordPress address (URL). That in
turn prevents phpThumbs from working with images
that are not under the directory where WordPress is
installed. Is that correct?

@Robert: I think you are competely right. I’ll try and have a look at it tonight and fix it. Thanks for the report!
