A script for converting images to different sizes inline, with support for server caching.
Very useful for creating multiple sizes of image urls from single images. Creates a thumbnail image depending on variables passed to it via get.
Images are cached on the server, so server processing overhead is only needed for the first time the script runs on a particular image.
Usage:
<img src="thumb.php?file=FILE&size=SIZE"> - to size the thumbnail to fit a square <img src="thumb.php?file=FILE&sizex=SIZEX&sizey=SIZEY"> - to size the thumbnail to fit a rectangle <img src="thumb.php?file=FILE&size=SIZE&quality=QUALITY&nocache=NOCACHE"> - to set a thumbnails quality
Where:
- FILE = the file to retrieve
- SIZE = the maximum size of the thumbnail in pixels
- SIZEX = the maximum width of the thumbnail (height adjusted accordingly)
- SIZEY = the maximum height of the thumbnail (width adjusted accordingly)
- QUALITY = an integer from 0-100 specifying the resulting jpeg quality of the image
- NOCACHE = an integer 1 or 0. If set to 1, the cached thumbnail is deleted and recreated (use if the source image changes)
Features:
- Server caching of images
- Creation of jpeg thumbnails inline, on the fly
- Can be used for non-local images, if allow_fopen_url in the php configuration is set to true
Requires:
GD Library
Installation:
The script should work with GD versions 1 and 2, and Linux and Windows servers
