When I add an image and include the max height and width variables on the relevant page the image is included and resized but is just a black box and not the actual photo ?

When I click the image I get the proper full size version ?

Any ideas ?

This would mean that the system is unable to grab the image then resize it. It could be a permissions problem or a path problem. Could it be something to do with the previous thread you made here?

Thanks for the hint Chris,

I seem to be getting somewhere.
I have changed the Image Uploads Path in Options - System Configuration to:

/home/sites/mysitename.co.uk/public_html/content/uploads/ and this now works for scaling the image in the news, however, the image link to enlarge now does not work as it has a link of :

http://www.mysitename.co.uk/home/sites/mysitename.co.uk/public_html/content/uploads/myimage.jpg

I assume that I can edit the coded link to compensate (I would also like to change the 'Image' alt or title tag, please can you point me in the right direction,

Thanks.

bbparser.php, towards the top you'll see this code

Code:


    global $image_maxheight, $image_maxwidth, $adminpath;
    $str = str_replace(" ", "%20",$str);
    $caption = stripslashes($caption);
    list($width, $height, $type, $attr) = getimagesize("$str");
    if(!$image_maxheight){ $image_maxheight = $height; }
    if(!$image_maxwidth){ $image_maxwidth = $width; }

Below that add this line of code which should hopefully fix it.

Code:


$str = str_replace("home/sites/mysitename.co.uk/public_html/content", "news", $str);

This will replace "/home/sites/mysitename.co.uk/public_html/content" with "news", "news" is the actual news directory so if you've named it something else you change it to that.

Thanks Chris,

I tried that but it stops the thumnail from showing again, changing the thumbnail path and it becomes black again ! but the linked larger image shows if I click the thumbnail.

Try this, the same line I said to add in my previous post, change it to this

Code:


$fullpath = str_replace("home/sites/mysitename.co.uk/public_html/content", "news", $str);

then if you scroll down a few lines until you see this

Code:


return "<div class=\"image_container\" style=\"width: $new_width" . "px\"><a href=\"$str\"><img class=\"fullnewsimage\" alt=\"image\" src=\"" . $adminpath . "?action=options&mod=imageuploads&width=$new_width&height=$new_height&thumb=$str\" /></a><br style=\"clear: both\" /><span class=\"image_caption\">$caption</span></div>";

change that to

Code:


return "<div class=\"image_container\" style=\"width: $new_width" . "px\"><a href=\"$fullpath\"><img class=\"fullnewsimage\" alt=\"image\" src=\"" . $adminpath . "?action=options&mod=imageuploads&width=$new_width&height=$new_height&thumb=$str\" /></a><br style=\"clear: both\" /><span class=\"image_caption\">$caption</span></div>";

Brilliant ! That sorted it.

I also changed:

Code:


 
alt=\"image\"

to:

Code:



title=\"Click to Enlarge\"

as alt doesn't work in Firefox,

Thanks,

Andy B.
