I would like to implement PHPThumb into my scripts. Below are the two scripts any ideas or suggestions, would be very much appreciated. Inspected every line of code and updated install instructions. This mod is tight except display still needs a fix...demo is currently at this site, <a href="http://php-evolved.com/">http://php-evolved.com/</a>. I also have forum threads going on this topic <a href="http://www.icyphoenix.com/viewtopic.php?f=24&t=8057">here</a> and <a href="http://evolution-xtreme.com/modules.php?name=Forums&file=viewtopic&t=4637">here</a>. As mentioned in those threads, everything is working, except PHP image generation scripts are not working (album_thumbnail.php and album_pic.php), or at least that appears to be the issue. Again, the port appears to be a success - except for the most important thing, the images will not display :( Today, I started from scratch and did the port once again - still the same result. The resolution MUST be something simple. I implemented a new image class and nothing. Tried rewriting the .htaccess files and still nothing. Even downloaded the FAP and attempted a port, and that was even worse. That's all good though, because I don't want everything that comes with FAP. The port of Album Mod version 2.0.56 is all I want - clean, simple and well integrated. Visit <a href="http://php-evolved.com">php-evolved.com</a> for yourself and see what I am talking about. Any help at all would be greatly appreciated. Below, I have attached the second port that I did today. Maybe this is above my pay grade, and I should leave it - but I do not wish to. Have come this far and everything else is working, it's just a shame that this one thing has tripped me up... -K album_thumbnail.php <code> define('IN_PHPBB', true); $album_root_path = $phpbb_root_path .

I know most can be done via plugins but not sure if you wanted to implement them as core methods because of their popularity in image manipulation. - grayscale - writeText (perhaps to write some text on the image when thumbnailing) - watermark (saw there was a plugin for it), but could also be labeled "merge" as a core method alex on "round corners" http://phpthumb.gxdlabs.com/forums/topic/zoomcrop#post-44 Mon, 06 Jul 2009 23:45:10 +0000 alex 44@http://phpthumb.gxdlabs.com/forums/ Is it possible to round corners with PHP thumb? nikmauro on "CONVERTING COLOR IMAGES TO B&W(GREYSCALE)" http://phpthumb.gxdlabs.com/forums/topic/converting-color-images-to-b038wgreyscale#post-111 Thu, 24 Sep 2009 00:06:56 +0000 nikmauro 111@http://phpthumb.gxdlabs.com/forums/ hello it is possible to change the color of the image to monochrome or B/W ??

Remove EXIF data will be really useful to create an image An idea? I love the project, I think integrating it into my framework Sorry for my english, i'm speak french :D skyzyx on "Feature Request: Memory-only images" http://phpthumb.gxdlabs.com/forums/topic/feature-request-memory-only-images#post-125 Fri, 16 Oct 2009 23:23:36 +0000 skyzyx 125@http://phpthumb.gxdlabs.com/forums/ I'm probably a special case in that I'm doing some nutty things with Amazon S3, but I'd like to be able to use an S3 class to fetch the binary image data, pass that into PHPThumb, and (besides show and save) add a third option for returning the processed binary image data to a variable that I can use to write back to S3. Basically, I'd like the entire resizing/converting process to happen in memory, so that I can pull from (and push to) S3 without having to create temporary files on disk or be forced to output them to the buffer. Within a few minutes I was able to write a plugin that did the memory output, but I don't seem to be able to pass image data in without hacking on the core library — and that's not something I want to have to do.

Sorry if my english is not very good. :) I'm a spanish web developer. I love your thumb tool, a great piece of software! but i need 2 little modifications to make it perfect for me. First... i want resize my thumb with only the "WIDTH" value or only the "HEIGHT" value. For example in a 800x600 picture, i resize the height to 100 (height = 100 and width = 133) and then crop in X=0 and Y=0 to 100x100 thumbnail. And finally... a parameter to apply a "Unsharp Mask" to the thumbmails (you can take the code here <a href="http://vikjavev.no/computing/ump.php" rel="nofollow">http://vikjavev.no/computing/ump.php</a>).
