Xlideit is a well-designed and easy-to-use image viewer.
The program opens with a full screen view of your Pictures folder. There's a thumbnail bar at the bottom of the screen, small toolbars top left and to the right, but most of the screen is taken up by the first image. (If you prefer a more conventional view then you can run Xlideit in a window, maybe add a folder pane, all in a click or two.)
The core controls are natural and intuitive. Click a thumbnail and that image is displayed; you can pan around an image by clicking and dragging; spinning the mouse wheel zooms in and out; double-clicking an image displays it full screen, then toggles to a normal view; and when you're finished, pressing Esc closes down.
Xlideit provides many ways to navigate through your images. You can click a thumbnail, click "next page/ last page" buttons at either side of the thumbnail bar, click and drag on a scroll bar, press the left/ right arrow keys, Home/ End, PgUp/ PgDn. There's even a touch-like feature, where dragging an image to the far left or right acts like a swipe and moves you backwards or forwards. And so, no matter how you normally like to browse your images, you'll probably feel comfortable with Xlideit immediately.
You're not restricting to viewing images, and Xlideit has a few editing tools: crop, flip, resize and rotate, as well as tweaks for brightness, contrast, saturation, hue and gamma. You're able to convert images between a few formats, too (JPG, PNG, BMP, GIF, TIF), view and clear their tags, and all these actions may be applied to multiple files in a single action.
