What software are you using?

If Lightroom Classic, select the desired photos, then select Photo->Create Virtual Copies (or equivalently press Ctrl-apostrophe)

thank you but im not exactly trying to make a virtual copy, im trying to add frames to my timelapse. So I have 800 photos I need to duplicate every signle image to make the timelapse longer. I remember there being a way to do it. Sequence image order is what I remember.

Lightroom classic

First, I don't know how to do what you want if it is not a virtual copy. What I do see is that Google finds about a dozen videos on creating timelapses via Lightroom Classic.

I think we need the actual goal to be clearer. Do you want, for example:

Images 1, 2, 3… to become 1, 1, 2, 2, 3, 3…

(each new frame is an exact duplicate that comes after each original frame)

or 

Images 1, 2, 3… to become 1, 1.5, 2, 2.5, 3, 3.5…

(in other words, do you need the new frames to be interpolated from the previous and next original frames)

or

Images 1, 2, 3… to become Images 1, 2, 3, 1, 2, 3…

(repeat same sequence of originals, multiple times, like a loop repeated)

Then it sounds like you can do what Rob_Cullen suggested already: Edit > Select All, then Photo > Create Virtual Copies.

What is the goal of creating these duplicate frames? Are you going to export a time lapse video from Lightroom Classic using the slide show workaround? Or are you going to export still frames to import into a video editing application? That might affect whether this is the right thing to do.

For example, if all you want to do is make each frame play for slightly longer, it could be a lot easier to not make duplicate frames in Lightroom Classic, load up stills in a video editor as a single clip, and adjust the total duration there.

Lightroom Classic cannot create real duplicates at all, it only creates virtual copies. What you might have done was export each image and add the exported image to the catalog.

If you want "1, 1, 2, 2, 3, 3…" as asked by @Conrad_C ,  AND you are creating the video (or Slideshow) within Lightroom-Classic, then the "Virtual Copy" suggestion as by @dj_paige is the way to go.  So easy to select all photos, and press [Ctrl+' ] as many times as needed for the number of copies required.

If you are creating the video 'outside' in another App, then Exporting several copy versions would be needed.
