Perguntas frequentes

What difference does it make?

ImageMagick can result in huge improvements in the quality of re-sized images.

Take a look at the supplied screenshot, or try it yourself.

Note that the new images tend to be slightly larger than those of the standard GD library, especially if you specify a very high image quality (95+).

How do I know if I have ImageMagick installed?

If you have the PHP module installed the plugin will find it. You can check yourself using the phpinfo() function. We also automatically check a common location for the ImageMagick executable.

If you have shell access to a Linux/UNIX server you can use “which convert” to look for the ImageMagick executable.

How do I install ImageMagick?

You’ll need full access to your server and a bit of technical know-how. If you do not have access you’ll have to ask the server administrator.

Don’t do it yourself unless you know what you are doing.

Most Linux distributions have a package for “ImageMagick”. Some have a package for “php5-imagick”. It is possible to install the PHP module using PEAR.

You can also find binary releases at http://www.imagemagick.org including a Windows installer.

I get a fatal error when activating plugin

Some webhosts (1and1 for example) need to add a work-around to the .htaccess file.

You might have to add the following line to your .htaccess file:
AddType x-mapp-php5 .php

You’ll probably have problems with various other plugins too unless you fix this.

There are now errors being thrown on the latest version of Wordpress and PHP. A warning about convert no longer being used, in place of magic.

Be careful if you’re using a Plugin like Real Media. The ImageMagick Engine does not respect the Directory structure the Real Media Plugin creates. This issue most likely does not affect many people, so it’s just a cautionary note to watch out for and not a complaint about the ImageMagick Engine Plugin. Although it would be a nice addition to this plugin as a cool refinement. Also on the subject of PNGs, the compression is not optimal. Again, not the fault of this plugin, but the underlying ImageMagick binary or PHP implementation. Here’s the quick data – Original Image 353 KB (3599 x 937), ImageMagick Engine 123 KB (768 x 200), Standard WordPress 117 KB (768 x 200), Corel Product 33 KB (768 x 200). And no, the above is not a mistake or typo when noting the size of the ImageMagick VS Standard Wordpress. And yes, the compression setting could be adjusted in the ImageMagick Engine configuration, but the above reflects the default of 70 (percent). Corel did an outstanding job given the image ended up a quarter of the size of IME or SWP. And zooming and inspecting the image on a 4K monitor showed no discernible difference. So sadly, doing it manually with Corel (or possibly other products) is the way for us to go right now. But still, this is a good plugin and this review is not intended to be derogatory or mean. But there are some refinements and improvements to made with it. Thanks for making the plugin.

The thumbnail regeneration could be a bit faster though. I have used it for longer than I can remember, at least 5 years.

Maybe even better. It uses ImageMagick Engine that is installed and allows me to easily regenerate all my images.
