When is the preview of an attachment generated

[Patrick_Vanhoof]

Is this preview generated on the fly every time someone clicks on the attachment, or is the preview also stored in the database and only regenerated when there has been a change?

Thanks.

Using Confluence 5.7.

Hi Patrick,

As far as I know, the preview is performed when you open the page, and every time you open that page. I'm not 100% sure since I couldn't find the article stating specifically that, so I'll leave this question open as such someone might have detailed information on this procedure.

Cheers,

Rodrigo

I have no idea, but I would love to know why you want to know this :)
