All of these examples use the PHP simple image manipulation class that I created.
Every now and then I write a batch image converter snippet that others might find useful. I figure I’ll post them here for my benefit and yours. These snippets will also serve as a way to better understand the class. As I come up with these in life, I’ll update this post.
All of these examples assume that you’ve already included the class in your file.
UPDATE: I’ve added support for PNG alpha transparency which makes this class significantly more useful. Changelog in the class code below.
I keep misplacing this class so I figured I’d post it here so that I know where it is.
I wrote/assembled this class because I wasn’t happy with any of the image manipulation libraries out there. They are either way too complex with a steep learning curve or didn’t work all that great. (I didn’t see any reason to load up a class with 3,000 lines of code just to resize or rotate an image.)
So here it is, a simple class that allows you to open an image, perform common operations, and save. There are no bells and whistles or anything exciting here. Just a collection of commonly used image manipulation functions: Rotate, Flip, Resize, Thumbnail (square and regular), and Crop.
A lot of the class code is original but some of it has been gathered over my life as a programmer from long lost sources. If you recognize your work, leave a comment and I’d be happy to cite you!
If you are a search engine marketer that has used Microsoft’s AdCenter, you probably have found it a bit annoying that when creating text ads, it doesn’t tell you how many characters you have left.
This means that the genius PPC ad-copy that you just wrote will only be rejected when you go to save because it is too long.
This Greasemonkey script detects when the new text ad dialog is visible, and will update the remaining characters that you have left to use as you type. Something that Microsoft should have done…. pay me MS, you lazy bastards.
This isn’t the only thing I find annoying about Microsoft AdCenter, but all the Greasemonkey scripts in the world won’t fix it. Click through for the script.

Browsers can save logins and passwords. Unless the autocomplete attribute is set to off, that is.
If you ever go to a website and wonder why it’s not asking you to save your password, it is probably because autocomplete has been turned off by the web designer.
Thanks Mr. Web designer, but I think I’ll be the judge of that.
First, let me say autocomplete=off is a good feature that keeps people who don’t know any better from doing something dumb. Looking at you, grandma.
But, if you are pretty confident in your internet self, and you use Firefox, you can use the following Greasemonkey script for Firefox to abolish autocomplete entirely from all websites you are viewing.
