Well for any who may be interested, here's some more I dug up: The iTXt chunk (international/Unicode text) is ripe for all sorts of uses. As you might expect, several enterprising people have written toolkits for exploring this. Here are a couple to get going: http://pmt.sourceforge.net/pngcrush/index.html Pngcrush is an optimizer for PNG (Portable Network Graphics) files. It can be run from a commandline in an MSDOS window, or from a UNIX or LINUX commandline. http://www.libpng.org/pub/png/apps/pngmeta.html http://pmt.sourceforge.net/pngmeta/index.html [OpenSource] pngmeta is a command-line program that extracts metadata (such as text annotations) from PNG images and formats it as HTML, SOIF, RDF/XML, or simple keyword/value pairs. It can be used as part of a CGI script, for example. http://entropymine.com/jason/tweakpng/ [GPL C++ source included] TweakPNG is a low-level utility for examining and modifying PNG image files. It runs on Windows 95 (or 98 or higher) or Windows NT. Nice interface, easy to use... For example inserting a fresh iTXt and pasting in a REBOL program! do %image.png ..becomes an interesting and viable proposition for X-internet. Images which can: - email or upload themselves - load directly into wikilogs [VANILLA] - associate intelligently with news [time] and map [locations] systems - enable smart and dumb i2i [image-to-image] applications - associate to others in load/play sequences by keyword, name, author, date, location, url, subscriber, popularity, context ... - ??? A REBOL Port of TweakPNG's iTXt fatures are needed. Is anyone into Rebolizing a few lines of C++ ??
