There are few alternatives:

An open source image viewer that allows you to directly zoom into large collections of tens of thousand of images from tiny thumbnails down to the images' original size fluently with short load times and no loss of interactivity.
Face detection and recognition support.
A small and fast image viewer. Because less is more.

It's been a while since I've used it (and I don't have a Windows box handy to test on) but I remember using an image viewer called JPEGView. From memory, I seem to recall it supporting the feature you need most: refreshing the display when the source file changes. In any event it is one of the few open-source image viewers for Windows that I found to holds ...
You can use IrfanView. This viewer is a mighty tool. I used it over the years and it is a great viewer, which also provided additional plugins.
The viewer is loaded very fast, without showing a loading window.
It supports your favourite grafik extensions and by installing plugins you can add several grafik formats.
Next and previous is done by the two blue ...
I don't know what's "similar to Picasa", as I don't use Picasa. But for everything else, Monte Gallery should be a good match.
Monte Gallery: Folder, Calendar, and Map view (source: Google Play; click images for larger variants)
As above screenshots show, you can browse by folders or calendar (your "date" requirement). You even can browse by location (...
You should have a look at digiKam, as of all the alternatives that I have checked it comes closest to fulfilling your requirements:
Full screen preview with basic zoom in/out abilites
Image thumbnail grid view of the folders
One thing, however, is that the fullscreen preview does not seem to support zooming in the version that I've tried (...
Have a look at OnTopReplica.
It allows you to have a window that is always-on-top. Although it does not let you directly select an image file, you can open the image that you want to work on in any image display program, select that window, and then select the subregion of the window/image that you want shown.
You can then set the opacity to multiples of ...
Of all (scarce) DJVU viewing software for OSX i so far find DJView the most feature rich among gratis software.
responsive continuous scrolling - Check
must be standalone (not browser plugin) - Check
retina support - No check
Other functions that I find very useful:
searching for text string if the text layer is present and copy text string into other ...
Windows Essential Photo Gallery can do most of what you ask:
Accurate facial recognition. It finds similar faces, you give them names. Over time you confirm/deny enough faces, and it will get them right all the time. The only issue I've found is with family (since my photos span decades) the accuracy starts to diminish.
Search is powerful. Filtering options ...
Sumatra PDF, though mainly used as a PDF reader, DJVU reader, and EPUB reader, can also open most image formats and automatically refreshes the document view, without locking the document if any other program is processing it. Quoting its web page, it opens:
PDF (.pdf) eBook formats: unencrypted EPUB (.epub) MOBI (.mobi)
Fiction Wise (.fb2, .fb2z, ....
The only Java application I ever heard of for this purpose is the JIExplorer. They attempt to offer an open-source alternative to ACDSee what is a rather popular commercial photo viewer. They support thumbnails but with respect to "tagging" this is very dependent of what you mean by that.
If you want to tag picture areas (such as offered by for example ...
Check out the FastStone ImageViewer. It's free, fast, user-friendly and contains a lot of useful features.
FastStone has a nice array of features that include
- image viewing
- red-eye removal
- color adjustments.
Its innovative but intuitive full-screen mode provides quick access to ...
Give nomacs a try. It's a free and open-source image editor that does all you require and more!
You can adjust the opacity of the application with Ctrl+J and Ctrl+Shift+J and lock/unlock (to keep on top) the application window with Ctrl+Alt+Shift+B.
I quite like it!
Adding this answer in case someone needs this in the future:
FastStone image viewer actually does work for this purpose. However, sometimes there can be a significant delay in the image refresh, which is what had me fooled when I posted the question.
None of the others do.
Challenger Comics Viewer allows you to scroll incrementally as well as page by page, (I think that is what you are really asking for), so that more than one image is visible on the page at a time.
Supported formats are JPG, PNG, GIF, WebP (Android 4.0+), BMP, PDF, CBZ/ZIP,CBR/RAR and ePUB
2 display modes (Simple View which displays pages one by one and ...
There is a good example here which makes use of the three.js open source library.
The code from the above page
While not a dedicated image viewer, Emacs is a highly extensible text editor. You can split it into several windows, horizontally or vertically using the shortcuts C-x 2, and C-x 3.
It is cross platform, so it runs on both Windows and Linux. But it only natively support images on Linux. For the Windows installation, you'll need additional GnuWin32 ...
You can easily monitor a given directory for new files using python, see here for 20+ answers, rawpy can convert almost any cameras raw format to an 8 bit RGB array in 3 lines of code, then you have a choice of possible ways to display the image and lots of online help. You could display the image for your self from within python or you can write your ...
Since I could not find anything that would sufficiently optimize this task, I made my own tool to do it:
Allows you to browse through folder A with large amount of images and copy the ones you like to folder B
Enter copies the image, Space shows the next image.
I use Honeyview for a while now on Windows, it's one of the closest to Picasa Picture Viewer I know. The UI is easy to customize and has lot of features.
Other alternative I use include (both available for Linux, Mac and Windows):
You can use Camera Roll for this. It allows to create virtual folders, and hide folders. So you could e.g. hide all folders but the one you want to see. Camera Roll is available at F-Droid and in the Google Play Store. Let's see how it fits your requirements:
Works on Android: sure, and only there (at least currently).
Gratis: More than that, it's open ...
For three years I am not Windows user anymore so what I am going to suggest is just based on my search and little checking reviews. Please check these projects. All are Free (as in freedom) Software:
There is a list of other image transparency utilities on AlternativeTo.net. The list will appear if you search for e.g. CThruView, Image Overlay Utility, or Osiva. The problem is that at present most of the free apps (including these just mentioned) are discontinued - only OnTopReplica seems to be current (or was in 2018). This latter isn't ideal because it ...
I wasn't able to open some TIFF files using standard Windows applications and even IrfanView. But I downloaded brava! reader and then I opened these files. I don't know why is this, maybe some specific options for these files.
If you have access to Visual Studio you can easily write one.
