Hello,

Wikitext editors can have media materials rendered using any arbitrary size (the thumbnails wikitext syntax). Each different size would produce a hit to the server backend which will generate a thumbnail for that size.

The following requests for comment is about having a consistent set of thumbnails sizes that are allowed to be rendered and let the client browser to do the up or down scaling.

It would be nice to discuss about it on the list and amend the document with any idea you might have :-]
