I am putting together a regional geocaching forum, and i would like to allow my users to show their geocaching.com stats image in their signatures. A typical image is like this (mine): http://img.geocaching.com/stats/img...uid=8386c231-1288-4c0f-93ae-0accf136bd15The default behavior of ubbthreads is to disallow images without an image extension. In a similar request made by someone else here back in October, Rick said: I'll have to put in an option. Right now it checks to see if the image is being generated by a script as a security precaution.
If you're comfortable with regex, it's blocked on line 639 of libs/bbcode.inc.php. I'm not particularly comfortable with regular expressions, but that code currently reads: function handle_img($url, $align="", $bypass_filter = false) {
if ($this->total_images >= $this->image_limit || (!$bypass_filter && !preg_match('#^[^\[\'"\]]+?\.(gif|png|jpg|jpeg)$#i', $url))) {
if ($align != "") {
return sprintf('[img:%s]%s[/img]', $align, $url);
} else {
return sprintf('[img]%s[/img]', $url);
}
}
I don't know if $bypass_filter was inserted after that October post or not, but changing it to true does allow images without extensions. I do not, however find where that option can be changed except by hacking the file, nor am I sure that it is not causing some other problem (besides the possible security issue) when I do. What can anyone tell me about this?

You could just build a custom tag for the geocache image via the CP (Tools & Info -> Content Rebuilder -> Custom Tag Editor)

Hmm. OK, I'm not sure what all I'm going to need for the markup in order to embed the image. New stuff for me. When I use: <img src="http://img.geocaching.com/stats/img.aspx?txt=View+my+profile&uid=\\1"> and enter the uid all I get is the uid between my beginning and ending tags.

OK, just had to keep plugging away at it. The following worked, displaying the image and linking it to the geocaching profile. Your examples over at UBBDev were most helpful. <?php
$export_tags = array (
0 =>
array (
'tag' => 'GeoStat',
'descrip' => 'Geocaching Stats',
'prompt' => 'Your Geocaching.com uid, like xxxxxx-xxxx-xxxx-xxxx-xxxxx',
'regex' => '([a-f0-9-]+)',
'markup' => '<a href=\\"http://www.geocaching.com/profile/?guid=\\\\1"><img src=\\"http://img.geocaching.com/stats/img.aspx?txt=View+my+profile&uid=\\\\1">',
),
);
?>

Of course I spoke too soon  the GeoStat tag works within the body of a message, but not in signatures, which is where I particularly wanted to use it. I was able to work around that by commenting out the lines in html.inc.php that disallow custom tags in a signature. Since this is the only custom tag I have enabled it shouldn't be an issue.
