People speak highly of IrfanView
. I myself don't use it but it's good from what I read, and it's free.
Instead, I'm still using ACDSee in one of its early incarnations (v4 on one machine because it's super-fast and super-lean and does exactly what I need and want in an image browser, and v5 on all other machines because of it's slightly prettier look and just about the same performance).
The current ACDSee PRO is a "BLOATED BEAST" and has far more in it than anybody could conceivably want or need. Plus it's priced too high. The earlier v4/v5 editions of ACDSee were very modestly and reasonably priced. Yes, I own it too (for its "professional image browsing and light-table features")... but never use it.
If only the company still sold these older smaller leaner faster legacy versions if you wanted one. Or, maybe they should just open up these old legacy versions a "free" (I know I'd have no problem sharing it with anybody who'd want it).
I have NEVER used MS's image viewers (Photo Viewer) or Explorer's interface to pictures. I've used ACDSee v4/v5 for the past 17 years, as do all the friends and family I can influence.
