pThumb

A fork of phpThumbOf. pThumb is a drop-in replacement for phpThumbOf and fixes many of its issues, adds a few new features, and improves performance.

pThumb uses the same namespace, settings and snippet name as phpThumbOf, so after it's installed any code using phpThumbOf will automatically use the new version instead.

Uninstall phpThumbOf before installing pThumb.

(You don't have to uninstall phpThumbOf first, but it makes things less confusing. If you uninstall phpThumbOf later, you'll have to reinstall pThumb.)

2.2.0-pl [10.11.2013]

Note: v2.2 has a new hash generation algorithm for cache filenames. After you update, cache images will be regenerated on access.

• Improve cache manager plugin; add Clean Level system setting

• Add several small optimizations for phpThumb

2.1.0-pl2  [06.10.2013]

• Update Resizer to v0.4.0-pl

2.1.0-pl

• Add a 'pThumb Cache' option. With this enabled, cached images aren't lumped into one flat directory but put into the cache in subdirectories which mirror part of the original image's path. The hash added to filenames is also much shorter. End result: cleaner, more semantic and SEO-friendly image URLs. See the documentation for more on configuring and enabling it.
• Several performance optimizations, including one when using phpThumb.
• Add pthumb snippet. It's the same as phpthumbof, only shorter to type :-)

2.0.0-pl

• Improve handling of paths, URLs and remote images
• [#2] Fix new_file_permissions setting
• Update Resizer to v0.3.1-pl
• Several minor bug fixes

2.0.0-rc3

• Update Resizer to v0.2.0-rc1, now a separate transport package.
• [#1] Fix protocol-relative URLs for remote images
• Fix &useResizer and &debug properties
• Several minor speed and efficiency improvements

2.0.0-rc2

• Add Resizer v0.1, a light-weight modern alternative to phpThumb. Resizer is built on Imagine, supports the Gmagick, Imagick and GD extensions and is considerably faster than phpThumb for scaling/cropping operations. Plus all the ZC options now work with GD. Enable in System Settings. Requires PHP 5.3 or higher.
• Fix a PHP warning the phpThumbOfCacheManager plugin was throwing.

2.0.0-rc1

• Major refactor for improved efficiency, especially when used multiple times on a page or when an image is already cached.
• Remove Amazon S3 support. I don't use or know much about this and rather than release completely untested and possibly broken code, I took it out.  If you'd like it added back and are interested in helping, please get in touch.
• Improve remote image handling. Originals are now downloaded to the cache to greatly speed up future access.
• Improve debugging output, including easy access to the phpThumb debug messages created when a thumbnail is generated (new &debug property for phpThumbOf).

1.0.0-beta2

• Add resource id # to error log message to make finding problem images easier

• [#54] [#50] Fix cache cleaning
