I apologize that I do not even know how to ask my question. I am creating/coding a page in a wiki. I want to have a little snippet of text that when the user clicks on it, the page changes to display an image, also in the same wiki, just as a full page with black background with the image in the middle of the page, not the page that gives all the information about the image. I hope this makes sense. On the page that has all the information about the image there is text "Open in media viewer" which, if clicked, shows exactly what I want my user to be able directly to click to. Something like I might want:
To see the picture, please click: [[ShowMeTheImage:File:My_picture.gif|here]]. Thank you.
