I notice that a number of applications appear to have cute little images of the local region, constellation or system. How do you dynamically create these? Is that even possible?
Any help much appreciated,

The best "cute little images", imho, are from www.tanx0r.org, but i don't think tanx0r has shared with the community the method to make those sexy images, sorry...

http://www.tanx0r.org/ is a great looking resource! Pity there's no contact details :(
Seems that the IGB has references like:
<IMG SRC="starmap:ids=20000509&markers=30003489::You are here::-::-">
<A HREF="showinmap:solarsystemID1//solarsystemID2//...//solarsystemIDn"> ... </A>
etc
Is it possible to get these out of game some how?

I think the eve-dev.net killboard is doing the same thing you want. Just download the src and look how its done

Both the killboard and my website generate png images through the GD library which should be installed on any decent apache/php/mysql server.
What you require is the eve database dump which is available from these forums and some means of querying this data and converting it into graphics.
From there all depends wether you want this to be done as a web application or standalone client application.

png+gd was obvious enough, tanx0r. :)
what was referred to, and what OP was mentioning, is THE means, not the backbone where it will run....
PS: postgres+lighttpd > apache+mysql

Yes, some tips would be nice.
"use apache and gd" is indeed a bit scarse. (and i agree with you Zath, pgsql+light ftw) :)

Some tables referred to (those starting with tanx*) will have to be taken out of the queries as you do not have those 
Enjoy.
Oh and here's the include file "getregion2.php".
<?php
// ---------------------------------------------------------------------------------------------------------------------

// uses the variable $zoomrate to allow zooming in and out. These values are also in the eveRegions table BUT those

while($row = mysql_fetch_array($result, MYSQL_ASSOC)) {$xmin = $row['x'];}
$result = query("SELECT x FROM mapSolarSystems where regionID = $regionID order by x DESC limit 0,1");
while($row = mysql_fetch_array($result, MYSQL_ASSOC)) {$xmax = $row['x'];}
$result = query("SELECT z FROM mapSolarSystems where regionID = $regionID order by z limit 0,1");
while($row = mysql_fetch_array($result, MYSQL_ASSOC)) {$zmin = $row['z'];}
$result = query("SELECT z FROM mapSolarSystems where regionID = $regionID order by z DESC limit 0,1");
while($row = mysql_fetch_array($result, MYSQL_ASSOC)) {$zmax = $row['z'];}
$xcenter = $xmin + (($xmax - $xmin) / 2);
$zcenter = $zmin + (($zmax - $zmin) / 2);
$result = query("SELECT regionName FROM mapRegions where regionID = $regionID limit 0,1");
while($row = mysql_fetch_array($result, MYSQL_ASSOC)) {$regionName = $row[regionName];}
$canvas = 1600; // canvas size in pixels
$middle = $canvas / 2;
$dimx = $xmax - $xmin; // map x dimension
$dimz = $zmax - $zmin; // map z dimension
$dime = (max($dimx, $dimz))/($zoomrate);
$multiplier = $canvas / $dime;
$xmin = $xcenter - ($dime / 2);// adjust minimal and maximal x, z values so our map covers a square instead of a rectangle.
$xmax = $xcenter + ($dime / 2);
$zmin = $zcenter - ($dime / 2);
$zmax = $zcenter + ($dime / 2);

And ofcourse "getuniverse.php":
<?php

// uses the variable $zoomrate to allow zooming in and out.
$result = query("SELECT * FROM mapUniverse where 1");
while($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
$xmin = $row['xMin'];
$xmax = $row['xMax'];
$zmin = $row['zMin'];
$zmax = $row['zMax'];
}
$xcenter = $xmin + (($xmax - $xmin) / 2);
$zcenter = $zmin + (($zmax - $zmin) / 2);
$canvas = 1600; // canvas size in pixels
$middle = $canvas / 2;
$dimx = $xmax - $xmin; // map x dimension
$dimz = $zmax - $zmin; // map z dimension
$dime = (max($dimx, $dimz))/($zoomrate);
$multiplier = $canvas / $dime;
$xmin = $xcenter - ($dime / 2);// adjust minimal and maximal x, z values so our map covers a square instead of a rectangle.
$xmax = $xcenter + ($dime / 2);
$zmin = $zcenter - ($dime / 2);

So there... Now I have "shared with the community"
I am currently trying to convert the maps on my site to 3d vector graphic ones which will be rendered client side, as the png generating takes up a lot of resources on the webserver.
More on that coming soon.

You're welcome.
To add landmarks to the map:
$result = query ("SELECT landmarkName, description, x, z, radius FROM mapLandmarks WHERE importance != 0 AND x >= $xmin AND x <= $xmax AND z >= $zmin AND z <= $zmax ORDER by radius DESC");
while($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
$x = $middle + intval($multiplier *($row['x'] - $xcenter));
$z = $middle + intval($multiplier *($row['z'] - $zcenter));
$rad = intval($multiplier * ($row['radius']));
if ($rad == 0) {$rad = 1;}
imagefilledellipse ($image, $x, $z, $rad, $rad, $landmark_color);
imagefilledellipse ($image, $x, $z, 5, 5, $landmark2_color);
imageellipse ($image, $x, $z, $rad, $rad, $landmark2_color);
imagestring($image, 3, $x+5, $z, "{$row['landmarkName']}", $lmarklabel_color);
}
All the mouseover popup and linking to solarsystems stuff on my website is done by generating html imagemaps. This is fairly straightforward and shouldn't be a problem once you managed to include the png maps in your code.
Be careful not to generate too many regions in your imagemap though as microshaft IE takes AGES to process those (in firefox this only takes a split second, proving once more that IE is really a ****ty browser).

Thanks AGAIN. :)
IE is indeed crap. I'm still amazed by people who have doubts about that.
And looking at the new acid3 tests.. IE is really pathetic.
Congrats to Opera, btw. :)
