Escenario: usuarios que suben imágenes a Chamilo con varios Mb de tamaño (ejemplo, 4-5 Mb) y las enlazan en portada o en cursos. Sería interesante añadir un plugin Chamilo que creara una miniatura (thumbnail) y al hacer clic en ella se mostrara la imagen original.

Sería interesante ya que sin disponer de conocimientos para editar las imágenes el usuario dispondría rápidamente de una imagen en miniatura sin tener que usar ningún editor gráfico.

En Joomla existe plugins para realizar estas tareas. Incluso uno de ellos tiene opción para generar una galería de imágenes, insertar marcas de agua, etc.


BK-Thumb is a multi-purpose image plugin for Joomla that can automatically create thumbnails and popups of the original images, as well as resize the full-size images or add a watermark to them. It can even scramble the images names so that people cannot guess their original non-watermark locations.

Here is a list of some of the new features in Multithumb 2.0:

Supports both popup images and images shown in content Watermark images can be true alpha blend PNG images or any GIF, JPG og PNG image with manually set transparent background color
User definable watermark position
Language packs
Installable language packs for Multithumb's frontend
Manual thumbnails
You can create your own thumbnails and let Multithumb use them instead
Thumbnail proportions
Choose between best fit (keeping aspect ration), crop to fit, fill out with background color, stretch (distort proportions)
Scrambled image names
Automatic resize of images
Can resize both popup images and images shown in content
Resize by pixels or percentage of screen size
New popup types: Slimbox, Greybox and Thickbox
Multihumb now supports six popup types: normal, lightbox, slimbox, greybox, thickbox, thumbnail expansion
Thumbnail expansion now works perfect with captions too!
"Intelligent" handling of compatibility issues with other javascript libraries
For example, if mootools.js is already included in your template, Multithumb will not try add it again
Auto-gallery with individual image descriptions
You can add a text file with the same name as the image used for the gallery, and Multithumb will use the content of this file for image descriptions
It will even create the description file for you, ready to fill out!
Link to main article in blog mode
Instead of showing a popup when viewing the article in blog mode, Multithumb can create a link from the first image to the main article.
Or it can just create a plain, inactive thumbnail
Works from sub folders out-of-the-box
You no longer have to modify the javascript files if you run Joomla from a sub folder on the server
Native thumbnail generation
Multithumb no longer uses an external thumbnail library
Informative error handling with javascript popup messages
Like if Multithumb can't find the watermark file, or if the server does not support the needed image functions
Extremely configurable
But because of that, also a bit confusing for new users :-)
Parameter override, allowing for multiple configurations even in same article
Most of Multithumb's settings can be overridden in the content by including the proper tags, like: {multithumb popup_type=greybox full_width=400} which will make Greybox the new popup style and images 400px wide
The override works until the end of the article or until it is overridden again.
There is even a handy online tool dedicated to creating the tags for you!
Many new options
Backend much better arranged
Improved and optimized code
