We understand that the most appropriate way of doing so may vary from case to case. See the Q&A below for some common examples.</p> <p><strong>Q:</strong> I want to use the footage in a YouTube video. Is it OK just to put the credit in the text description?<br/><strong>A:</strong> No, as this is hidden inside a tab and therefore not visible as we request. Also it is not visible if the video is embedded in another website. In the special case where you cannot credit the video visibly, please include the credit line ‘burned in’ or overlaid on the video, or clearly visible as a credit at the end.</p> <p><strong>Q:</strong> I want to upload an ESOcast to my YouTube channel, or embed this in my blog. Do I need to add a credit ‘burned in’ or overlaid on the video?<br/><strong>A:</strong> ESOcast videos already have a credit at the end, so you do not need to edit it.</p> <p><strong>Q:</strong> I am a producer for a TV programme and wish to use your images and footage. Do I need to overlay the credit on the image?<br/><strong>A:</strong> You do not need to, provided the credit is clearly visible and reproduced in full at the end of the programme.</p> <p><strong>Q:</strong> I am making an electronic game. Where should I place the credit?<br/><strong>A:</strong> As long as the credit <em>is clearly visible to all users</em> and reproduced in full, for instance in a splashscreen, all is fine.</p> <p><strong>Q: </strong>I am a picture editor for a newspaper/magazine. Some of your credits are kind of long. Can’t I just use the first part of the credit?<br/><strong>A:</strong> No. Please reproduce the credit in full. This should normally be on the page which the picture is presented on, or on the facing page.</p> <p><strong>Q:</strong> I am a picture editor for a News Agency. We prefer to use our own name as credit for the images and not tell anyone from where we got them. Is that ok?<br/><strong>A:</strong> No. Please reproduce the credit in full. This should normally be on the page which the picture is presented on, or on the facing page.</p> <p><strong>Q: </strong>I want to use a picture on the cover of a book/magazine. Does the credit have to appear on the cover?<br/><strong>A:</strong> No. Provided it is clearly visible and identified as being the credit for the cover image, the credit can appear in another prominent place in your publication. This could, for example, be the back cover, the inside front cover or the editorial page.</p> <p><strong>Q:</strong> Do I need to contact all the people named in the credit line for permission to use an image or video?<br/><strong>A:</strong> No. Images and videos published on eso.org are, unless explicitly stated otherwise, cleared for reuse without needing to contact the individuals or organisations listed. Their names must not be removed from the credit, however.</p> <p><strong>Q:</strong> Do I need to send you a physical copy of any products I have made using your imagery or footage?<br/><strong>A:</strong> No, an electronic copy (e.g. a photograph or a PDF) is fine. And it is in any case not mandatory to send a copy.</p> <p><strong>Q:</strong> I would like to digitally alter or manipulate an image. Is this OK?<br/><strong>A:</strong> Yes.</p> <p><strong>Q:</strong> I would like to edit, expand or cut text from ESO.
