The "Auto Image Resizer" is a state of the art WordPress Plugin which reduces your uploaded images to the maximal used image dimensions of your WordPress website.
If the uploaders (author, member, whoever) browsers supports html5, gears, flash or silverlight the images will be resized directly on the client otherwise the server will do that. So the plugin works in every case regardless of the clients browser or OS.

The free Lite Version
In the free version of the plugin you can test the plugin as long as you want but with a small limitation: The free version can handle sepia images only. Of course in the pro version you can upload true color images, too! You can find the free version of the plugin here.
How it works
- Download the plugin and install it on your WordPress website or blog
- Configure the plugin in the WordPress backend (or use the default options)
- If a user uploads a new image to the media library, to a post or a page (or a custom post type) the plugin analyses the image dimensions automatically and unnoticeable.
- If the uploaded image is bigger than the defined maximal image dimensions it will be reduced to the maximal height and width without cropping or deforming it.
- If the uploaders browsers supports html5, gears, flash or silverlight the images will be resized directly on the client before uploading them.
- Then the reduced version of the uploaded image will replace the "large size" version of the image.
This saves your web space the traffic of the website visitors.
Installation
After you have purchased the Auto Image Resizer Plugin you get it as .zip archive. You can upload this .zip archive in your WordPress Backend in Plugins -> Add New -> Upload to your website or blog.
(Seasoned WordPress users can also upload the extracted archive to wp-content/plugins/.)
After installing the plugin you need to activate it in Plugins -> Installed Plugins -> Auto Image Resizer -> Activate.
Configuration
As soon as the plugin is activated it is operable. By default the maximal image dimensions from your current media settings will be used and there is a small set of default options.
Maximal image size
You can change the maximal image dimension in Settings -> Media -> Image sizes -> Large Size.

Image quality
You can change the image quality in Settings -> Auto Image Resizer -> Image quality.

Custom Image Sizes
Some Plugins and Themes use custom image sizes for post thumbnail images or header banners. The Auto Image Resizer take care of the image dimensions of other components so your images could be some pixel bigger than your "large size" option.
Automatic Updates
On the Settings page you can enable or disable the automatic updates. To make use of the automatic updates please enter your account details in the corresponding option box.

I have a photography site and I get a lot of I/O errors if I upload the full picture size. It keeps timing out. I suspect that it is the size of the file. Will this plug-in reduce the size of the files prior to uploading, or does it do it while uploading? Please advise.
Hi Frank, I would recommend you try it with the free lite version.
Our members add thumbnails within their comments via a plugin with a maximum size of 250 pixels but I also want to allow them to upload images to the library with a maximum size of 770. Will the pro version of the plugin allow us to set different upload settings for thumbnails and full size images?
Hi Graham, the Auto Image Resizer does only resample the biggest image.
Hi-
Will this plugin autosize Featured Images such that they won't crop at, say, 50x50? Rather, an original 200x100 image would end up at 100x50 in the Featured area rather than being just a crop of the middle of the original 200x100? That's what I need. Thanks!
The Auto Image Resizer does not crop images at all.
Hi,
Is it possible to set minimum size of pictures? so no more small pictures,always have same size pictures on my website
It means no small pictures or no big pictures
I do not think that this would be a useful feature. The idea is to save space and traffic and not to blow up images sizes.
Hello,
Testing the free version and it makes all images black and white, removes all colors.

Hi Rune, the lite version can only handle gray-scaled images. The Pro Version of the plugin can handle true color images, too.
