I don't seem to find an answer to this yet. I have set up Lightbox and need to change the size of the image that pops up when you click on the "thumbnail". I'll try to describe what I want. On the page I have an image (screen shot of an index page - for my portfolio). My second image is almost the same, but it is the whole index page, not just what is visible section at the top. So when it comes up, it is tiny like the whole page is fitting to the screen. I want it to be big like the first one and scrollable because it is long. Does that make sense?? Maybe an image would help? Thank you in advance for any help.
In yellow, is what I want it to do. Both overlay and background can scroll. I don't care about that so much.
