 * `widthStep` (160) - Caching is impossible unless we limit the number of image variations. The default, 160, gives us `160, 320, 480, 640, 800, 960, 1120, 1280, 1440, 1600, 1760, 1920, 2080(2048)` - 13 variants, and keeps bandwidth waste very low.
 * `jpegQuality` (90) - The jpeg compression quality to use on low-dpr displays ( < 1.5 dppx).
 * `jpegRetinaQuality` (80) - The jpeg compression quality to use on high-dpr displays, where artifacts are much less visible.
+* `enforceCss` (false) **ALPHA** - Sets img.style.width to max the pixel value of the css `max-width` every time the img.src value is also updated. Only useful for emulating max-width on IE6/7/8, enable via conditional comments.

     Add window.slimmage.beforeAdjustSrc callback function - this allows users to inject behavior between noscript parsing and img.src edits.  
     Replace adjustImageSrcWithWidth with getImageInfo, make adjustImageSrc responsible for more. Simplifies certain kinds of extension, such as background image support.
 * 0.2.6 - Fix typo causing ‘undefined’ is null error; affects 0.2.4+. 
-* 0.4.0 - Only fire `window.slimmage.readyCallback` on first `checkResponsiveImages()` and when there have been actual modifications to images. Add window.slimmage.webpTimeout to increase likelyhood of webp usage working. Disable verbose output by default. Apply `maxWidth` after `widthStep` instead of before (lowers upper bound from 2080 to 2048). Stop inverting jpeg and webp quality values.

Fix IE6/7 setAttribute bug; class value was not copied from noscript element. Add `window.slimmage.enforceCSS` setting; can emulate max-width on IE6/7/8, which lack an implementation.
