On the one hand this is a smart piece of work, figuring out how to do something that a lot of people want to do, in a way that works for the vast majority of systems. Another good reason for using an Apache/PHP setup (the IE of the server world...). On the other hand, it seems to ignore some of the reasons for not using images for text. People who are capable of dealing with content that includes images, and therefore download them, may not be able to read your particular font in the header. People with some vision might use the white-on-black setting offered as a standard display mode by any serious operating system, with a font that suits them. Within these constraints they are happy to try and look at an image, if it's more or less explained and they are just getting an additional idea. With a heading turned into an image, they're back to the old problem - control of contrast is dodgy (in most cases it should work, because most designers are too smart to make headings almost unreadable, but not all). I am intrigued by how it works for people who download some images (the way I work on my phone, and from time to time on my laptop) - to have the alternative available unless they decide to try the image. Or vice versa. I'll look over the code in more detail. Yesterday I came across the first example I met of SVG used totally in the wild on a completely commercial site (for ordering a taxi). It's a bit over a year since I started coming across it in the wild in non-commercial settings, where people are often prepared to experiment more - some with crazy ideas, some with thinking about the standards and how to implement them as they are designed. Stylesheet switching is starting to offer the user a chance to get a site the way they want it.smarter developments in the mobile world are doing even more in that direction - after realising that a technically better Web isn't as popular as one that includes what is on _THE_ web (the lesson of the WAP/iMode work) people have mostly gone back to trying to make a technically better version of the existing web. There is, of course, more or less infinite material for debate on what is actually technically better. And given that there are constraints in the real world, we also get to discuss which trade-off is better. I can see a motivation for trying to use images for text, whatever WCAG says, and finding a workaround that solves the same problems is a reasonable strategy. A lot of the people who have come up with very smart solutions are seriously committed to standards, and are looking to make the Web better - and in general they are the kind of people who do. Our job, as accessibility people, is to mmake sure we know as much as possible about why a checkpoint or a common practice exists, and whether a new technique meets the same needs. On the other hand, a massive number of these needs can be met by simple things like CSS' Web Fonts (little used when they came out years ago, available now in SVG so likely to get some slow growth). Authors, and more seriously the tools that the vast majority of authors use, go on supporting something like the easiest common denominator. That is, they neither go for something that can work in every tool, only a selection of them (there are grounds for making a selection...) nor something that takes a very imaginative or architecturally clear view of a better future. Like Todd Fahrner's Image Replacement technique, this is a piece of careful thinking from someone applying real brainpower. I hope it stands up better to the curiosities of the real world of accessibility better than Todd's approach. But there are a couple of things that make me nervous. One of those things is our tendency to accept very quickly something that they can offer to designers, without testing it heavily first. We don't yet have better alternatives (for all i believe that well-implemented SVG is smarter, we simply don't have enough long-term experience with it in this group to explain way, how to use it right, and what to avoid). People have commercial imperatives, and quite sensibly they are prepared to do something good rather than not putting anything online until they can do it better. But that should make us redouble our efforts to findd something better than what we offered first. (One of the things I like about this group is that people are doing precisely that :-) avagoodweekend. And don't forget the Aerogard. (Don't worry, that last sentence is an obscure and irrelevant reference to my childhood. Geoff Deering might get it...) cheers Chaals On Thu, 24 Jun 2004 15:25:29 -0400, John Foliot - WATS.ca <foliot@wats.ca> wrote: >> The W3C's WCAG states: >> >> Priority 2 - 3.1 "When an appropriate markup language >> exists, use markup rather than images to convey information." >> >> It can't be clearer than that.
