I've noticed several posts where there are a series of photos stacked up. How is that done? I seem to be able to insert one per post. I'd like to put up 3 to show how Topaz AI worked for a Hawk in a field shot.
The term “stacking photos” applies to photos that are merged as in HDR or flattened Photoshop layers. It has nothing to do with posting multiple images on UHH. To post multiple images on UHH read the instructions at the top of the “Photo Gallery” section which explain the requirements and the mechanics of posting. Best holiday regards!
Short answer; YouTube "Photo Stacking".

If you are referring to posting multiple photos at one time.
You do it one at a time. Click on "Choose File" and pick your first image, check "store original" if you want people to be able to see the full image by doing a download, click on "Add Attachment" and wait for it to finish, do not click on "send" and never click on "Preview". To add photos just repeat those steps, you can go up to 10 images. After you have all your images posted you then click on "Send". If you have more images (say it is a photo essay of a trip you took) you click on "Reply" and add more images to your own thread in a new post - as many times as needed.
If you are referring to people posting a "Stacked" image either HDR, Focus Stacked or Panorama those are processes done in editing software to produce effects impossible or very hard to do with one shot. The image posted is the result of the stacking and merging of multiple photos.
HDR - a scene with more dynamic range than your sensor can handle - you keep the camera in one place and change the f-stop (most common way) or shutter speed, or ISO to produce images exposed for say "shadows", "normal" and "highlights" (sometimes more exposures are used, depends on the scene and the goal for a final image.)
Focus Stack - multiple images are taken with the focus point in different places so the depth of field overlaps and when blended with the correct software the final image uses only the in focus sections of each frame to produce an image with sharp focus from near to far. Often used by landscape, macro or product image photographers (I saw an image done of a custom made guitar that involved 150 individual shots looking at the guitar length ways at a class taught by the photographer.)
Panorama shots are stacked but in a different way. Using some method to keep the camera level take multiple shots (I go left to right) with each shot overlapping the ones to each side to allow the software something to blend. Then you put the images into the software but chose "panorama" instead of "stack" and the software will stitch the images together end to end to produce a wide panorama image. At my daughters graduation ceremony from Pre-med I did a six shot one hand held in light rain of the faculty standing on the covered stage. Of course the frames were not perfectly evenly aligned but cropping off the uneven top and bottom edges worked fine.
Forgot one other common stack - Astro photographers will take multiple shots (some times hundreds) of the night sky and then stack them - to take advantage of the randomness of digital noise so that hopefully they all cancel each other out and leave a solid black sky with stars, moon etc instead of all those colored speckles of electronic noise. Then they don't have to spend hours making all those speckles black at the pixel level during Post Processing.
Answered succinctly and thoroughly. Thanks.
It would be great if everyone on here was as nice and courteous as Linda from Maine is. Linda I hope you have a blessed and Merry Christmas and a Happy New Year
