Easy-to-use image viewing software

There are many picture viewing software encountered in work and life, and there are several that are really easy to use, and I recommend an IrfanView, which is extremely powerful and rich in plugins

Characteristic:

You can install both versions on the same system, just use different folders. For example: install the 32-bit version in the Program Files (x86) folder and the 64-bit version in the Program Files folder (install 32-bit plug-ins to IrfanView-32, install 64-bit plug-ins to IrfanView-64, do not mix plug-ins and IrfanView bit versions)
The program name and icon have some extra text in the 64-bit version to make it easier to distinguish

Version comparison:

Advantages of IrfanView 64-bit over 32-bit versions:

It can load very large files/images (image RAM size over 1.3 GB, suitable for special users)
Faster for very large images (25+ megapixels, loading, or image operations).
"Only" runs on 64-bit Windows (Vista, Win7, Win8, Win10, Win11).

Advantages of IrfanView 32-bit over 64-bit versions:

Runs on both 32-bit and 64-bit Windows
Load all files/images normally needed (maximum RAM size is approximately 1.3 GB)
Less disk space is required
All plugins work: not all plugins are (also) ported to 64-bit (like OCR), some 32-bit plugins must still be used in 64-bit versions, and some have limitations (see "Plugins32" folder)
Some older 32-bit plugins only work in compatibility mode with IrfanView-64
Command-line options for scanning (/scan, etc.) are only available for 32-bit (64-bit TWAIN drivers are rare = > If something goes wrong, scan with IrfanView-32)
