"/modules/newbb/images/blank.gif" is generated directly by png hack when an image is forbidden/incapable to access.

That's why I suggested to disable png hack.

The reason for forbidding image access could include hotlink protection or some other unknown issues.
I have checked dean_collins' images, all exist.
So, I still suspect it is a hotlink protection problem.

Ok, here is the fix. I don't know what the cause of the problem is, but at least I figured out the solution. :)

edit modules/newbb/include/functions.php

Find the lines:
if(file_exists($imageuri)){
$size=@getimagesize($imageuri);

and modify them to say:
if(file_exists(XOOPS_ROOT_PATH.$imageuri)){
$size=@getimagesize(XOOPS_ROOT_PATH.$imageuri);

I am a 2-day newbie to XOOPS and cbb, but I know this: for some reason, imageuri does not include the full XOOPS path. files_exists is crapping on the bogus path name (like '/modules/newbb/images/blah.gif') when it expects the full unix path.

Maybe someone smarter than me can find out why?

Re: CBB forum, big problem

You are an absolute freaking legend....!!!

sensational work.

Working perfectly. Can someone tell me how we get this modified so that this change is implemented in so no one else has to go through this problem.

You're a champion, if you ever think I can repay the favour somehow dont hesitate to ask.

Cheers,
Dean

Thanks guys!

Seems that the processing in functions.php::newbb_displayImage() is not fully valid:
$imageuri=str_replace(XOOPS_URL,XOOPS_ROOT_PATH,$image);

I am going to check and make a fix in next release.

Update:

mainfile.php (in the XOOPS root) defines the constants XOOPS_URL and XOOPS_ROOT_PATH. Most people probably have a value in XOOPS_URL liks "/xoops/html". However, since I am using a test subdomain, which points directly to my xoops/html directory, my XOOPS_URL is '' (empty string). These problems are happening w/ newbb because XOOPS_URL is ''.

So, the problem is not exactly with the lines I pasted earlier, although that will fix the problem, too. The 'real' problem is the str_replace line just about the lines I pasted here.

The str_replace doesn't work when XOOPS_URL is empty. The newbb module is trying to provide a real pathname to file_exists() and getimagesize(), but the str_replace has no effect. Again, I think this will only cause problems when XOOPS_URL is ''.

Add some logic around your str_replace like this, and see if that works, too.

[in include/functions.php]
Quote:
.
.
.
$image .= '.'.$image_type;

// 2005-09-14: REH: added logic to test for XOOPS_URL. Without it, the str_replace has no effect when
// XOOPS_URL is empty.
if (XOOPS_URL != '') {
$imageuri=str_replace(XOOPS_URL,XOOPS_ROOT_PATH,$image);
} else {
$imageuri= XOOPS_ROOT_PATH.$image;
}

if(file_exists($imageuri)){
$size=@getimagesize($imageuri);
.
.
.


The file also has a snafu like this one. Look for the line:
Quote:
$indeximage_select->setExtra("onchange=\"showImgSelected('img', 'indeximage', '/".$imgdir."/', '', '" . XOOPS_URL . "')\"")


and replace that line with this:
Quote:
// 2005-09-14: REH: added logic to test for XOOPS_URL. Without it, the str_replace has no effect when
// XOOPS_URL is empty.
if (XOOPS_URL != '') {
$indeximage_select->setExtra("onchange=\"showImgSelected('img', 'indeximage', '/".$imgdir."/', '', '" . XOOPS_URL . "')\"")
;
} else {
$indeximage_select->setExtra("onchange=\"showImgSelected('img', 'indeximage', '/".$imgdir."/', '', '../../..')\"");
}


The magic is in that last line. Note: This only works for me since '../../..' gets me back to the XOOPS root from where I have this module installed. your mileage may vary. Hopefully the author can patch the module so we can get rid of my spaghetti code. .

Oops ... I forgot to mention the other filename with that last bug. The file that uses the $indeximage_select->setExtra business is admin/admin_cat_manager.php, in the function editCategory().

Solution for test:
function newbb_displayImage($image, $alt = "", $width = 0, $height =0, $style ="margin: 0px;", $sizeMeth='scale')
{
    global $xoopsModuleConfig, $forumImage;
    static $image_type;

    $user_agent_is_IE5 = newbb_isIE5();
    if(!isset($image_type)) $image_type = ($xoopsModuleConfig['image_type'] == 'auto')?(($user_agent_is_IE5)?'gif':'png'):$xoopsModuleConfig['image_type'];
    $image .= '.'.$image_type;
[b]    $imageuri=preg_replace("/^".preg_quote(XOOPS_URL,"/")."/",XOOPS_ROOT_PATH,$image);
    if(!preg_match("/^".preg_quote(XOOPS_ROOT_PATH,"/")."/",$imageuri)){
        $imageuri = XOOPS_ROOT_PATH."/".$image;
    }[/b]
    if(file_exists($imageuri)){
        $size=@getimagesize($imageuri);
        if(is_array($size)){
            $width=$size[0];
            $height=$size[1];
        }
    }else{
        $image=$forumImage['blank'].'.gif';
    }
    $width .='px';
    $height .='px';

    $img_style = "width: $width; height:$height; $style";
    $image_url = "$image."" style="".$img_style."" alt="".$alt."" align="middle" />";

    return $image_url;
}



Thanks for your help.
