Best PHP Image Crop Class

Question

I'm designing a website and I need to:

• Upload the image
• Validate that it's an image (and not, oh I don't know.... a virus :) )
• Resize the Image
• convert to jpg

Essentially basic image upload

Instead of writing my own I'm trying to find a php class that let's me do all this, because as Jeff Atwood said, "never design what you can steal"

Now before you go ahead and downvote because I didn't do my research, I did:

Googling this brings up a huge amount of results, which is the problem, I don't know which results are useful and which are trash!

So far, Ive found:

• https://stackoverflow.com/questions/4997127/php-class-to-upload-image-from-url-and-resize-it (I know it looks like a duplicate, but its not because it is asking for a URL fetcher)
• http://net.tutsplus.com/tutorials/php/image-resizing-made-easy-with-php/

• http://www.phpclasses.org/package/2181-PHP-Process-files-and-images-uploaded-via-a-form.html
• http://www.digitalgemstones.com/code/tools/ImgUploader.php

Does anyone have any experience with these classes? Can you recommend an outstanding image upload class?

My personal favorite Image Manipulation Library is WideImage. It makes is ridiculously easy to do that kind of task.

WideImage::load('pic.png') ->crop('center', 'center', 90, 50)->saveToFile('cropped/pic.jpg'); 

As for validating if it is actually an image or not, use finfo or PEAR::Mime_type. I personally prefer PEAR::Mime_Type. It uses finfo but it's just simpler to use.

Using finfo:

$finfo = finfo_open(FILEINFO_MIME_TYPE); $mimetype = finfo_file($finfo, $filename);  $isImage = (preg_match('#^image/#', $mimetype) === 1); 

Using PEAR::Mime_Type:

$mimetype = MIME_Type::autoDetect($filename);  $isImage = MIME_Type::wildcardMatch('image/*', $mimetype);
