Imsanity

説明

Imsanity automatically resizes huge image uploads down to a size that is
more reasonable for display in browser, yet still more than large enough for typical website use.
The plugin is configurable with a max width, height and quality. When a contributor uploads an
image that is larger than the configured size, Imsanity will automatically scale it down to the
configured size and replace the original image.

Imsanity also provides a bulk-resize feature to selectively resize previously uploaded images
to free up disk space.

This plugin is ideal for blogs that do not require hi-resolution original images
to be stored and/or the contributors don’t want (or understand how) to scale images
before uploading.

What is Imsanity?

Imsanity is a plugin that automatically resizes uploaded images that are larger than the configured max width/height

1. Will installing the Imsanity plugin alter existing images in my blog?

Activating Imsanity will not alter any existing images. Imsanity resizes images as they are uploaded so
it does not affect existing images unless you specifically use the “Bulk Image Resize” feature on
the Imsanity settings page. The “Bulk Image Resize” feature allows you to selectively resize existing images.

2. Why aren’t all of my images detected when I try to use the bulk resize feature?

Imsanity doesn’t search your file system to find large files, instead it looks at the “metadata”
in the WordPress media library database. When you upload files, WordPress stores all of the information
about the image.

3. Why am I getting an error saying that my “File is not an image” ?

WordPress uses the GD library to handle the image manipulation. GD can be installed and configured to support
various types of images. If GD is not configured to handle a particular image type then you will get
this message when you try to upload it. For more info see http://php.net/manual/en/image.installation.php

4. How can I tell Imsanity to ignore a certain image so I can upload it without being resized?

You can re-name your file and add “-noresize” to the filename. For example if your file is named
“photo.jpg” you can rename it “photo-noresize.jpg” and Imsanity will ignore it, allowing you
to upload the full-sized image.

Optionally you can temporarily adjust the max image size settings and set them to a number that is
higher than the resolution of the image you wish to upload

5. Why would I need this plugin?

Photos taken on any modern camera and even most cellphones are too large for display full-size in a browser.
In the case of modern DSLR cameras, the image sizes are intended for high-quality printing and are ridiculously
over-sized for display on a web page.

Imsanity allows you to set a sanity limit so that all uploaded images will be constrained
to a reasonable size which is still more than large enough for the needs of a typical website.
Imsanity hooks into WordPress immediately after the image upload, but before WordPress processing
occurs. So WordPress behaves exactly the same in all ways, except it will be as if the contributor
had scaled their image to a reasonable size before uploading.

The size limit that imsanity uses is configurable. The default value is large enough to fill
the average vistors entire screen without scaling so it is still more than large enough for
typical usage.

6. Why would I NOT want to use this plugin?

You might not want to use Imsanity if you use WordPress as a stock art download
site, provide high-res images for print or use WordPress as a high-res photo
storage archive. If you are doing any of these things then most likely
you already have a good understanding of image resolution.

7. Doesn’t WordPress already automatically scale images?

When an image is uploaded WordPress keeps the original and, depending on the size of the original,
will create up to 4 smaller sized copies of the file (Large, Medium-Large, Medium, Thumbnail) which are intended
for embedding on your pages. Unless you have special photographic needs, the original usually sits
there unused, but taking up disk quota.

8. Why did you spell Insanity wrong?

Imsanity is short for “Image Sanity Limit”. A sanity limit is a term for limiting something down to
a size or value that is reasonable.

9. Where do I go for support?

Questions may be posted on the support forum at https://wordpress.org/support/plugin/imsanity although I may move support to the helpscout platform we use for EWWW I.O.

  • Add a network settings to override the individual plugin settings text

評価

Still works great

I’ve used Imsanity on many websites over the past few years and it always works. It’s great for any sites that allow the public or multiple users to upload photos. I tested it today by uploading a photo of 5472×3648 resolution at 16.8 mB filesize. It automatically resized appropriately to 1920×1280 at only 375 KB. And this was through a gallery field for Advanced Custom Fields on a custom post type. It’s very versatile!

A great solution

Use this plugin on all my sites. Works great. Always recommend to everyone.

These digital cameras now a days are taking huge >16mb images that users upload. This plugin prevents the uploads dir from being out of control.

Brings back sanity to your images

This plugin is a site saver, because I upload my images directly from my iphone and they are huge. This plugins reduces image sizes very smartly.
I love it.
