PDF Thumbnail Generator


I've used this on multiple sites and have found it invaluable.



While I've struggled with getting the required ImageMagick set up and working on a few servers – each one requiring a slightly different approach owing to different OS and security settings – this is not the fault of the plugin or plugin author.



I'm not sure what one reviewer means by this being built-in to WordPress; to the best of my knowledge that is incorrect.


Invaluable for building document libraries and the like

<p><strong>Now with added JSColor color picker!</strong><br />
<strong><em>Our plugin now loads with JQuery No-Conflict mode!</em></strong></p>
<h3>Additional Information</h3>
<p>= Requirements =<br />
PHP 5.x<br />
GD image library</p>
<h4>Issues</h4>
<p>Godaddy 4GH has a strange cacheing problem, no matter what you set for cacheing over-ride, they cache things for upto a minute and typically longer so if you notice that your images don’t immediately display then wait at least 2 minutes and refresh and they’ll be there. However, if you know of a solution to this mess please let me know and I’ll add you to contributors line. Turns that after you mash “regenerate images” if the graphics still have not updated, if you do a ctrl+f5 (forced refresh of your browser) then new graphics appear. That makes it sound like a browser issue. But it isn’t. If anyone has some ideas. Please let me know so I can fix this or stop worry about fixing it in case it is a browser issue.</p>
<p>Site5 webhosting has a really old version of PHP and I believe the GD library. So if you aren’t getting generated banners and you are somehow based off of Site5.com that is most likely the problem. However, I am told that they are switching to the latest version of PHP in the next few weeks, so we will soon see.</p>
<p>Implementing the planned CSS rendering engine will alleviate both issues.</p>
<h3>TODO</h3>
<p>= REWRITE!!! =<br />
Completely rewrite the plugin as it is hugely unmaintainable now. This must be done before anything else on the TODO list can be accomplished. I am currently looking for people to help with getting this done and for future development of the plugin. Benefits are new friends, additional promotion of your site and a warm fuzzy feeling!<br />
* I am thinking of going with classes as well as segmenting the file into multiple parts.</p>
<h4>Cookies</h4>
<p>By using cookies I’ll be able to add a banner/graphic skipping mechanism. Example of this would be that you would tell the banner to not show for 5 pageviews, or skip for 5 then show up. By using cookies, we can control this on the user and when the cookie count matches, we will display the graphic in question.</p>
<h4>Store for Future</h4>
<p>Add database routines to store everything you create or upload for future retrieval at any time. Also, needed for scheduling.</p>
<h4>CSS Functionality</h4>
<p>Switch to a completely CSS driven routine. Which will solve resolution issues and transparency issues. Because the GD library sucks. For some reason GD is forcing me to use the “black” color for the transparency. It is not agreeing with the code at PHP.net. Going CSS will solve this issue. I just have to wrap my mind around CSS now. 😀</p>
<h4>Transparency</h4>
<p>Fix transparency issue. I checked with browsershots.org and it seems the images are drawing great. So if I can solve the issue where GD insists on black being the only transparent color for the background, things will be better. This will be a non-issue when the css rendering engine is implemented.</p>
<h4>Scheduling</h4>
<p>Allow the decorations to be scheduled to appear on any given time and day. This is great for the holidays, special events and more!</p>
