An update to snippet 1718 (http://www.djangosnippets.org/snippets/1718/). This update lets you pass an image URL string as well as a model ImageField instance. This means that you can then create thumbnails on demand for images outside of model
The above code contains the file name fetches random images from the database. Using the JQuery this image is displayer in the page
PIL IcoImagePlugin is twelve year old and it can't handle recent Windows ICO files. Here is a function that handles all ICO versions and preserve transparency. Usage: # Load biggest icon from file image = load_icon('icon.ico') # Save third icon as PNG load_icon('icon.ico', 2).save('icon.png')
Something I end up doing all the time, making a boolean variable show up as a nice image. With this code you can do the following: `{% boolean_img user.is_active %}` And get the following output: `<img src="/media/icons/accept.png" alt="True" />` All you need to do is use the custom templatetag code, load it in your template and use the `boolean_img` tag. **Adjust templates, html and images where needed**
**So you can upload rectangular pictures but still have square thumbnails.** "Scale to **fill**" instead of the out of the box "scale to **fit**" you get with `Image.thumbnail`
Given such code: class ProductImage(models.Model): fullsize = models.ImageField(upload_to= "products/%Y/%m/%d/") display = AutoImageField(upload_to= "products/%Y/%m/%d/",prepopulate_from='fullsize', size=(300, 300)) thumbnail = AutoImageField(upload_to="products/%Y/%m/%d/",null=True,default='/media/noimage.jpg')) display will be automatically resized from fullsize, and thumbnail will default to /media/noimage.jpg if no image is uploaded Note: At some point the code broke against trunk, which has now been updated to work properly
Don't forget to replace "self.image" by your image field name from your model ex ( self.cover ) replace Product by your model name works pretty well :)
Django Ajax Image Uploader, this what we do for: https://github.com/agusmakmun/dracos-markdown-editor/
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/)
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...

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.
