EasyPhpWipeJPG is a script to remove all EXIF, IPTC, and comment information from JPEG images. The resulting image will be 100% identical to the original image without any quality loss (binary wipe). Why shoud you remove EXIF, IPTC & Comment information? For privacy considerations (the image might contain sensitive data (camera brand, model, GPS location, etc.)), SEO considerations (unwanted tags from manufacturers like "LEAD Technologies Inc. V1.01"), and to reduce file size. It offers the option to create backups of the original images, which you may restore or remove later. It can work on images in a single directory, or it can search and include images from the entire subdirectory structure. The images will be processed in batches (no limit to the amount of images).
Zebra_Image is a compact (one file only), lightweight, object-oriented image manipulation library, written in and for PHP, that provides methods for performing several types of image manipulation operations. It doesn’t require any external libraries other than the GD2 extension (with which PHP usually comes pre-compiled). The code is heavily commented and generates no warnings/errors/notices when PHP’s error reporting level is set to E_ALL. It can rescale, flip, rotate, and crop images. It supports loading and saving images in the GIF, JPEG, and PNG formats and preserves transparency for GIF, PNG, and PNG24. It can re-size images to an exact given width and height and still maintain aspect ratio.
