Yep (you can see it in the attachment). I have created a ImageChartPreloader to preload the ImageInfo from DOMSource. What I can see is that the originalURI is null. 1) Should I do something at some place to specifiy that uri? (where, how...) 2) However even if the originalURI is null as I can get all the infos from the source it's ok. But what MimeType should I give to the created ImageInfo? (I've tried some, but I always get the same error : no suitable loader/converter combination...etc) 3) I've tried to solve my problem with the preloader, but if it's not the right way for doing it (ex: maybe setting some attributes to the Document is?) tell me. 4) Please take à look at the attachment, so you can tell me what is missing.
