Django Media manager with celery image optimatization

You will extend the one i put in mediamanager app.

1. Custom file/image field

- Which opens a large modal with a iframe of the mediamanager

- there should be a type option so that only the required file type can be selected

- When selecting a certain file it adds the file on save

2. Media manager

- When file has been uploaded, save the original file in map /orig while you make thumbnails in the most common sizes and also compress them accordingly (Celery task).

- All images should be converted to webp with fallback on png (so both have to be available)

- If browser does not support webp, png has to be shown

- Losless compression is necessary

- Directories have to be available in mediamanager (models already made)

3. Compression - Celery task

- First: Lossless compression

- Second: Create all common thumbnails in png

- Third: Convert to webp

- Both formats have to be saved

4. File deletion

- File has to be removed from server asswell

5. Storage

- Default will be static

- Option external storage

6. Django template tag to use an model image

for example:

{% show_thumbnail 'heightxwidth' 'object' %}

- Can be used within srcset

- If thumbnail size does not exist, take closest or create on the fly

Standard will show .webp but fallback .png if .webp is not supported
