i probably would not have decided this had been trendy quite a few years ago but it’s amusing precisely how age adjusts the means by which you perceive different ideas, thanks regarding the write-up it really is pleasing to browse some thing smart now and then instead of the regular nonsense mascarading as blogs on the net, i’m going to enjoy a smattering of hands of zynga poker, take care

Hi, It doesn’t seem to work for me. I get no errors, it just displays nothing. I am dropping the following code in to my html:

Thats correct right?

Thanks

Hi, it works very well, but you have a typo error over here:

imageline($img,0,0,$MAX_WIDTH,$MAX_HEIGHT,$c2);
imageline($img,$MAX_WIDTH,0,0,$MAX_HEIGHT,$c2);

The variable $c2 doesn’t exists, it should be $c

Essentially, you call it like this:

< img src="/thumbnailer.php?img=/site_images/image.jpg&height=300&width=300" />

does that make sense?

And the BASE URL is just what it sounds like, what its set to depends on how you wish to use it. If all your image files will forever be located in http://www.yoursite.com/site_images/ then that would be your BASE URL and you could call it like: src=”/thumbnailer.php?img=image.jpg&height=300&width=300″. Otherwise, if you will vary where the image is coming from, then you can just specify your BASE URL to be http://www.yoursite.com and call it as shown in my first example.

Good luck.

LOL, great site looking through many things you have published. Just a little lost on how this is working.

I tried as directions show but a little messed up on base url and image url setup.

whether the $IMAGE_BASE is the site url or the site url with /images/ tagged on it. is there a zip working of this that I can download

thanks.

Mark.

I understand the script, but I’m not understanding how to use it. Too new to Apache and too used to ASP.Net, I reckon. I don’t really know how to find the problem.

The script runs without errors, but using an image link as described in the example link, above, I don’t seem to be passing any parameters and get the “FILE NOT FOUND” message (I’m apparently not passing the image_width and _height parameters, also; slight changes to die without a width or height shows they aren’t being passsed to dfn_thumbnailer, too.

But when I hard-code the image name in the thumbnailer script, I get a text-view version of the page for output.

If you would not mind, could you give a bit more detail about how this is used for the stone dumb like me?

Thanks.

Nice!

To be safe / prevent root path disclosure, you might put intval around the mw and mh variables before using them, and using a file_exists on the file
