Be careful with Irfanview and XNView as these are free strictly for personal use (non commercial). An open-source alternative I've been using is: https://nomacs.org/. - Source: Hacker News / 7 months ago
For Linux users looking for something similar to IrfanView, nomacs is the closest I found to IrfanView since I moved away from Windows: https://nomacs.org/. - Source: Hacker News / about 1 year ago
How that cmyk profile is shown depends on the image viewing app too and if it [the app] can show that colour profile. Have you tried opening the image in a webbrowser, if it's updated and your monitor has the specs for it, try drag&drop the image to an open browser tab. As for img viewing app you can try nomacs.

If you delete photos or folders in the photos app, they are moved to the recycle bin. If you remove an album you have made, it does not delete the photos. If you disable the Photos app, you will need a 3rd-party image viewer. FastStone IrfanView (Definitely get the plugins if you use this.) Nomacs XnView MP ImageGlass. Source: over 3 years ago

Nomacs, an open-source image viewer, has garnered a solid reputation within the software community, particularly among users seeking lightweight and versatile alternatives to default photo viewing applications. The software competes with similar products like IrfanView, XnView MP, and FastStone Image Viewer, offering features that hold broad appeal, especially for users focused on image editing and viewing across multiple platforms.
Nomacs is praised for its simplicity and effectiveness in handling a wide array of image formats, including RAW images. Its ability to synchronize multiple viewers on the same computer or via a local area network is particularly valued in collaborative environments, such as architectural projects where image comparison is crucial. The program's agility and lack of latency when opening images or scrolling through galleries are frequently highlighted as significant advantages.
The software supports basic image editing functions like adjusting brightness, contrast, saturation, hue, gamma, and exposure, making it a convenient tool for users who require minor modifications without turning to more robust graphic design software. Its cross-platform availability (Windows, Linux, and Mac) and adherence to open-source principles (GNU Public License v3) further enhance its appeal, promoting flexibility and transparency.
In public discussions, Nomacs is frequently recommended as a robust alternative for those dissatisfied with default photo applications, such as Microsoft's Photos app. Users transitioning from other operating systems, notably those familiar with IrfanView, often find Nomacs a suitable replacement due to its similar functionality and user-friendly interface.
However, there are notes of concern about the software's development lifecycle, with some users questioning the frequency of updates based on observed activity on platforms like GitHub. Despite this, the consensus remains positive, with many continuing to recommend Nomacs for its no-frills approach and reliability.
Moreover, Nomacs finds favor for its fast performance in opening and managing images, minimalistic design, and capacity to work smoothly even on systems with modest specifications. The open-source nature further appeals to users who prefer software that is both free and customizable, aligning with parallel offerings from the broader community of free photo organizers.
Overall, Nomacs maintains a strong position in its product category due to its commitment to providing a lightweight, efficient, and free-to-use solution. It stands out in the crowded field of image viewers for its synchronization capabilities, accommodating a range of file formats, and offering essential editing features without unnecessary complexity.
