Now I tried the supplied demo files, and all work fine, except phpThumb.demo.gallery.php. Here I get the error <code>failed to open "/demo/images/"</code> I tried various settings for the path variables but was not able to get it to work. In a Google search I found many test sites with the same problem, but no solution. What do I need to enter for $basedir etc. to get the gallery demo to work on XAMPP? Thank you!

On some slower servers the caching is a really nice feature to have. Am I not using the software correctly, or is it actually missing from version 3? If it's missing, are there any plans to introduce it? Whilst leaving this message, I'd like to say what a great bit of software I think php Thumb is.

I'm sorta guessing that most browsers can handle jpgs & gifs - w3c has this to say on the matter.... <blockquote>Attributes of this type identify the allowable content type(s) of an associated URI (usually a value of another attribute on the same element). At its most general, it is a comma-separated list of media ranges with optional accept parameters, as defined in section 14.1 of [RFC2616] as the field value of the accept request header. In its simplest case, this is just a media type, such as "image/png" or "application/xml", but it may also contain asterisks, such as "image/*" or "*/*", or lists of acceptable media types, such as "image/png, image/gif, image/jpeg". The user agent must combine this list with its own list of acceptable media types by taking the intersection, and then use the resulting list as the field value of the accept request header when requesting the resource using HTTP. For instance, if the attribute specifies the value "image/png, image/gif, image/jpeg", but the user agent does not accept images of type "image/gif" then the resultant accept header would contain "image/png, image/jpeg". A user agent must imitate similar behavior when using other methods than HTTP. For instance, when accessing files in a local filestore, might cause the user agent first to look for a file logo.png, and then for logo.jpg. If a value for the content type is not given, "*/*" must be used for its value. For the current list of registered content types, please consult [MIMETYPES].</blockquote> So, placing a <code>In its simplest case, this is just a media type, such as "image/png" or "application/xml", but it may also contain asterisks, such as "image/*" or "*/*", or lists of acceptable media types, such as "image/png, image/gif, image/jpeg". </code> type statement would keep me in alignment with the rules - My question then is, what would be, if any, the effect of removing the code from your library with those directives in ? -- Yeah, I know I'm a pain in the ass, but, please try to see it my way - I already have a header section to look after all my pages, and I would be most pleased to be able to adapt to use your fantastic php-code.

I have a special field for image classes, so i want to resize them with <a href="http://www.site.com/show_imagex.php?file=%field%" rel="nofollow">http://www.site.com/show_imagex.php?file=%field%</a> this works in my code but i have lots of images, around 20+ per page, so i think it takes a hit on the server. So i was thinking to save them and display them, something like this: <code><?php require_once 'ThumbLib.inc.php'; $fileName = (isset($_GET['file'])) ? urldecode($_GET['file']) : null; if ($fileName === null || !file_exists($fileName)) { echo "imagine lipsa"; } try { $thumb = PhpThumbFactory::create($fileName); } catch (Exception $e) { echo "exception"; } if(!file_exists('static/'.$fileName)) { $thumb->adaptiveResize(170, 80); $thumb->save('static/'.$fileName); } $new = PhpThumbFactory::create('static/'.$fileName); if(file_exists('static/'.$fileName)) { $new->show(); } ?></code> So basically get the field name, save in static, and show it. Now i dont know if this uses resources each time i call it, to create a new thumb, or it takes it from static.

But the images are never displayed. In Firefox, I see only a text coming up. for example: <a href="http://localhost:8888/fmdisconvac/public/news/shownewsimage?img=foto+2.jpg." rel="nofollow">http://localhost:8888/fmdisconvac/public/news/shownewsimage?img=foto+2.jpg.</a> In firefox i see the symbol for a missing image. This is the code in my shownewsimage.php file $img; $fileName = (isset($_GET['img'])) ? urldecode($_GET['img']) : null; if ($fileName !== null) $fileName = $this->path.$fileName; if ($fileName === null || !file_exists($fileName)) { echo "image does not exist. (".$fileName.")"; } try { $img = Zend_FreimsImage_ThumbLib::create($fileName); } catch (Exception $e) { echo "error occured"; } $img->show(); atDev on "Set options after initialization" http://phpthumb.gxdlabs.com/forums/topic/set-options-after-initialization#post-37 Wed, 01 Jul 2009 19:08:38 +0000 atDev 37@http://phpthumb.gxdlabs.com/forums/ Is there a method we can use to set options after we create the object using the factory instead of passing it in? alex on "save files- permissions" http://phpthumb.gxdlabs.com/forums/topic/save-files-permissions#post-12 Wed, 17 Jun 2009 07:55:50 +0000 alex 12@http://phpthumb.gxdlabs.com/forums/ When using the file save functions, the permissions are set in a way that I can't delete file via <a href="http://FTP." rel="nofollow">FTP.</a> Is there a setting to change the default permissions? alex on "getting around header restriction" http://phpthumb.gxdlabs.com/forums/topic/getting-around-header-restriction#post-10 Wed, 17 Jun 2009 02:11:41 +0000 alex 10@http://phpthumb.gxdlabs.com/forums/ In the documentation, I found the following line: <blockquote>When showing an image, the library sends a header before the image stream. Because of this you CANNOT show an image directly in the middle of your page since output will have already started. It's very much the same as how you can't just toss a session_start() in the middle of your page. You can, however, get around this restriction in a relatively easy way, which we'll take a look at later. </blockquote> However, I can't find the easy way to get around the restriciton that is mentioned. Could you please explain how to do this?
