PhotoarchivePlugin

PhotoarchivePlugin is a nice plugin to show your photo archive or album in different views. You can add a description to each picture and define the picture size for individual views.

  • Future releases will get something like templates to have full control over the layout.
  • Now a multiplatform offline Photoarchive application is in work. It will become the user interface for simple storing, describing and uploading to your TWiki Photoarchive. But it needs time.

Syntax Rules

These are the rules to add a Photoarchive to your twiki web.

  • Add %PHOTOARCHIVEPLUGIN% to a twiki topic or
  • ... add %PHOTOARCHIVEPLUGINRANDOM% for single random image including.
  • Create a new topic with name <TOPICNAME>Photoarchive
  • Attach your pictures to <TOPICNAME>Photoarchive
  • Add your picture definitions in the following form to this topic:

<PA_IMAGE>
IMAGEFILENAME
</PA_IMAGE>
<PA_HEADER>
SHORT IMAGE DESCRIPTION
</PA_HEADER>
<PA_DESCRIPTION>
LONGER DESCRIPTION FOR THIS IMAGE
</PA_DESCRIPTION>
<PA_IMAGE>
NEXT IMAGEFILENAME
</PA_IMAGE>
... etc.

  • Each tag must start at the beginning of the line (no spaces) and end with a newline!
  • You can overwrite the preferences for images and layout in the topic where you add the %PHOTOARCHIVEPLUGIN% or %PHOTOARCHIVEPLUGINRANDOM% placeholder. To use overwriting from topics you have to add PhotoarchivePlugin_ in front of each settingname. E.g. instead RANDOMWIDTH you have to use PhotoarchivePlugin_RANDOMWIDTH

Examples

  • This is a sample entry for <TOPICNAME>Photoarchive

<PA_IMAGE>
image_001.jpg
</PA_IMAGE>
<PA_HEADER>
My first image in Photoarchive
</PA_HEADER>
<PA_DESCRIPTION>
This is my first image which is shown by PhotoarchivePlugin.
It has no special purpose but you can see how it works.
</PA_DESCRIPTION>
