Hi everybody ! I'm using this method to send HTML mails : xwiki.mailsender.sendHtmlMessage(...) in a groovy script and it works perfectly, but I have trouble with pictures. Indeed, in the content of my mail, I have a <img> tag with a "src" attribute pointing on a picture located on my xwiki. When i'm logged on my XWiki, I can see the pictures when I open my mail. When I'm not logged on XWiki, I can't see pictures beacause I suppose I need authentication : does somebody know how I could do to solve this ? I think I have to send a HTTP Authorization Header in the content of my HTML mail in order to reach the picture but I don't know how to do, I 've tried with "http-equiv" in the <meta> tag but no success. Thanks for your help ! Regards, Pierrick
