pywiUpload - Prepare a gallery of images for Piwigo
|
||||
===================================================
|
||||
|
||||
This Python script prepares a gallery of images for Piwigo gallery
|
||||
script (see http://www.piwigo.org/). It resizes images, creates
|
||||
thumbnails with some options (rename images, squared thumbs, ...), and
|
||||
upload images to a FTP server.
|
||||
|
||||
Dependencies
|
||||
------------
|
||||
|
||||
- Python Imaging Library (PIL)
|
||||
- exiv2 (for exif datas)
|
||||
- ConfigObj
|
||||
|
||||
on Ubuntu:
|
||||
> sudo apt-get install python-imaging python-pyexiv2 python-configobj
|
||||
|
||||
on Fedora (as root):
|
||||
> yum install python-imaging pyexiv2 ?
|
||||
|
||||
The script should also work on other system (Windows, Mac) but this has not be
|
||||
tested yet.
|
||||
|
||||
Installation
|
||||
------------
|
||||
|
||||
- unzip files where you want
|
||||
|
||||
Usage
|
||||
-----
|
||||
|
||||
go in the directory of images to process and launch the script:
|
||||
> cd /path/to/images
|
||||
> python /path/to/pywiUpload/pywiUpload.py
|
||||
|
||||
Options:
|
||||
- launch the script with the directory of images to process in argument:
|
||||
> cd /path/to/pywiUpload/
|
||||
> python pywiUpload.py -i /path/to/images
|
||||
- you can also provides a config file (useful if you have different settings)
|
||||
> cd /path/to/pywiUpload/
|
||||
> python pywiUpload.py -c mypywiUpload.conf -i /path/to/images
|
||||
|
||||
Settings
|
||||
--------
|
||||
|
||||
Adapt setting to your needs in the configuration file (pywiUpload.conf):
|
||||
- Size of images and thumbnails
|
||||
- JPG quality
|
||||
- Thumbnails prefix
|
||||
- FTP parameters
|
||||
|
||||
Options
|
||||
-------
|
||||
|
||||
Some features are optionnal (1=enable / 0=disable):
|
||||
- Add a copyright on the images
|
||||
- Keep big images
|
||||
- Keep exif datas
|
||||
- Make squared thumbnails
