I think what GIF supports that the others don't is the ability to essentially include the parameters in the GIF file itself? I seem to recall reading that it used text blocks that the GIF format allowed, but that most graphics programs would clear when they saved a GIF file ... I don't think JPG supports that- does PNG? (...)
wrJPGcom (I used a DOS package for converting tga to jpeg when PSP did not support progressive scan) writes comments into JPEGs. I think EXIF data in JPEGs from cameras is comments. I might still hav JPEGs into which I piped fractint formulas and parameter files; not that a lot of people knew they were there. I think if you want to publish (or otherwise archive) formulas or parameter files, then it is better to do that separately, so that people who are not interested in math can easily skip it, and people who are so can find it. Then comes that handy web construct called an anchor (link). On my local system, though, all of my published fractals hav their own directories. That way, I can call one file chromo and one file lumo in each directory, plus batch files for jenerating them (ignoring the one that fractint writes, because it will be the same) if I want to change colours. And that way, I can also write a batch file for rejenerating everything, say if I come across more frames for 25" by 22". If you are any good with key-operated software, you run XP, and you know what "program /?[enter]" does, what a readme.htm file is for, or what the F1 key usually does (help menus), then you need fractint in your path to really appreciate some of the throughput on this list. Control Panel/System/Advanced/Environment Variables/Path/Edit [end];c:\fractint (or wherever you extracted a zip file to--Square brackets indicate a single key). Winfract works, though I can't say it has all the same features, or that it understands what to do when I double-click on a .par file. Here and in sci.fractal, people are much more likely to be interested in software. Everywhere else, I skip the math or sketch it out in English. To answer your last question, David, http://wiki.tcl.tk/10564 That is how you write comments into a PNG. I do not see a utility for doing it. That is source code. I think I am getting a lot of noise in my search from web pages that invite comments.
