I remember testing out the ImageGlass photo viewer last year and was impressed with the speed at which it could shuffle through photos, but I wasn’t very fond of the interface. When I recently checked back in on the project I noticed that a technical preview of ImageGlass 1.5 was available, and it is looking pretty good. Keep in mind that this is still pre-beta, but they’ve really cleaned up the interface which actually makes it a lot more likely that I’ll use this again in the future.
Because of how ImageGlass preloads upcoming images I’d have to say that this is one of the fastest apps I’ve used when it comes to flipping through a library of high-resolution images. If you’re reviewing a large folder of images this can alleviate the pains that Windows Photo Gallery causes due to the time you have to wait for some of the images to fully load. If that sounds like something you can relate to then I’m sure the speediness of ImageGlass will be awfully refreshing.
The only problem I have with the app is that while you can open a folder of images there is no option to tell it to look in subfolders as well, which means it will only display the photos at the root of the directory you select. Depending on how you organize your photos that might be a deal-breaker, but I wouldn’t rule it out yet because that should be an easy fix for the developer.
