ImageGlass vs Picasa Comments
Positive comment by BarnMTB · Sep 28, 2025
While ImageGlass is only a photo viewer and not a full-on Photo Management software, ImageGlass can be configured to look and work pretty similarly to the Picasa Photo Viewer (part of Picasa), albeit it doesn't match Picasa's Photo Viewer completely. ImageGlass itself is a great piece of software.

digiKam vs Picasa Comments
Positive comment by Elros Telperien · Dec 15, 2018
Great photo and tag management tools. It's also apparently the only program, from the ones listed, that has facial recognition features (although not great in comparison to Picasa's).
Negative comment by tomater · Jul 12, 2022
Well, the UI of digiKam is a torture. Using it after Picase is like going from UI back to command line. It's packed with features, yes, but UI overcomplicated far beyond what is necessary. Tabs on top, tabs on the left, tabs on the right, and yes, each window section can also have tabs...

Digikam is a much more advanced editor and manager, not neaarly as simple as Picasa.

Fly Photos vs Picasa Comments
Positive comment by BarnMTB · Oct 1, 2025
Fly Photo is not a photo management software, but it's specifically created to replicate Picasa Photo Viewer (part of Picasa & discontinued alongside it), and it has been getting pretty close to Picasa. Fly Photo's main goal is to be fast, so the developer turned off some animations by default; but once you toggle those settings back on, it's very close to Picasa.
