I've reimplemented the code I found somewhere on the web within my models file. The earlier version was incapable of converting all formats to JPG while this code converts all formats and compresses all of them successfully.
You only have to put the code in some of your models.py and to have django-fiber installed in your system. Every image uploaded using Fiber admin dialog will be automatically resized and thumbnailed. Or whatever you need to do with it.
PushPinImageField is a Django form field that is a sub-class of an ImageField. The field accepts an image to upload and based on certain settings, notably the size of the resulting image, the sizes and colors of 3 different borders, as well as the color of the push pin, a re-sized image is created with a colorized push pin in the top-center. A live demo of the field as well as more detailed usage instructions are available as a [blog entry](http://www.robmisio.com/blog/2/).
Very straightforward way to display a thumbnail in the admin using [django-thumbnails-works](http://pypi.python.org/pypi/django-thumbnail-works) . django-thumbnails-works requires [cropresize](http://pypi.python.org/pypi/cropresize/#downloadsInstaller) (which requires and installs PIL). Add 'thumbnail_works'to INSTALLED_APPS in settings.py and here you go. Tested in django 1.3 alpha.
A custom templatetag for inlining image in the browser. The principe is to base64 encode the image and avoid a http request. There is a cache handling, you just have to specify a writable directory. An example of the utilisation (template part): [http://djangosnippets.org/snippets/2267/](http://djangosnippets.org/snippets/2267/) The explication on [http://raphaelbeck.wordpress.com/2010/11/14/make-inline-images-to-improve-performance-with-django-template-tags/](http://raphaelbeck.wordpress.com/2010/11/14/make-inline-images-to-improve-performance-with-django-template-tags/)
The example of the Image inlining template tag lib which inline images in the browser instead of making an Http request.
This is the snippet of rafacbd but upgraded... (http://djangosnippets.org/snippets/955/) Now support keep the aspect ratio or not, changing the size string (x1, x0) this choice use pil.resize or pil.thumbnail. Remember change the variable CAPS NAMES of the cleanup code. This cleanup function get the original main image file name and create a regexp similar to "[filename]_[width]x[height]x[ratio].[ext]" and remove all thumbs. By example if the main image is spain_rulez.jpg the script remove by example spain_rulez_100x100x1.jpg spain_rulez_200x150x0.jpg etc... etc...
The above code contains the file name fetches random images from the database. Using the JQuery this image is displayer in the page
Example mixin for creating and removing thumbnails on a model. Also adds some methods for accessing an url for an image size. It might be a better idea to use a custom image field instead of this approach. Idea for getting the image url for different sizes from http://code.google.com/p/django-photologue Example usage <pre> >>> p.get_small_image_url() u'http://127.0.0.1:8000/site_media/photos/small_someimage.jpg' </pre>
This custom processor is meant for use with sorl-thumbnail to add letterboxing functionality. Add to your THUMBNAIL_PROCESSORS like so: `THUMBNAIL_PROCESSORS = ( 'sorl.thumbnail.processors.colorspace', 'sorl.thumbnail.processors.autocrop', 'sorl.thumbnail.processors.scale_and_crop', 'sorl.thumbnail.processors.filters', # custom processors 'utils.processors.ltbx', ) ` and then use in your templates like so: ` {% thumbnail model.img_field 200x150 ltbx as thumb %} <img src="{{ thumb }}" width="{{ thumb.width }}" height="{{ thumb.height }}" />` Enjoy.
** Image on demand view ** I often post photos on photography fora. Most fora want you to place a link to a photo somewhere on the net, but different fora have different rules. Some fora want you to stick to a maximum of 800 pixels wide, some 700 pixel and some even strange values like 639 pixels. My own site uses 600 pixels so I end up resizing images all the time. Since I keep my originals with my gallery as well (hidden for public viewing) resizing on the fly would be a nice asset. I'm using my previous snippet to apply a slight unsharp mask for better web display of my photos. ** usage ** This snippet takes the url to my photo application which is a simple link using the pk of my photo table and adds 'width'.jpg to the end (some fora check if the link is an image based on extenstion) The view takes the width requested and creates the resized image from the original full size image or takes it from the cache for display on demand. To prevent a dozen directories I use a setting to specify which widths are allowed, providing room for several versions of the same image. Any improvements are appreciated since I'm still rather inexperienced in Python and Django.
This is the complete image_processor.py module, allowing you to add an image containing an arbitrary piece of text. I use this to label the horizontal axis of a skills-matrix report. Credit www.renewtek.com for paying me to do this stuff!
