HoneyView

My best default image viewer. Super fast. RAW support. Wisely customizable. Thoughtful functionality. Portable. One of the best software I ever use.

Extremely fast image viewer (the fastest I've used so far), with full 64-bit support, a nice user interface and a good number of supported formats. It also has a high-quality Lanczos image interpolation filter, which makes your pictures look a lot better when zoomed in.

The "select image" feature is a thumbnail+list view, it just sucks.
It really needs a good thumbnails view feature.

I was looking for a light alternative to xnview to open JPG files. Based on comments on this site i narrowed it down to Nexusimage viewer and HoneyView image Viewer. In the end i chose HoneyView for the reasons stated below, but i suggest you try them both out as both of these programs are magnificent.

Pros: Multi-Monitor Support. Keyboard shortcuts. Saves recent folder path BUT NOT last opened image. Remembers Last window size. Supports Scrolling Next, Previous image with mouse. Supports Spacebar & Backspace to view Next, Previouis image, Supports Dragging of image files unto its window, Supports FULL ZOOM: Win+ Win-- OR Num +, Num --, Num *. Option to Show in Windows Explorer. Able to open multiple instances. Uses very little system resources. It was very stable on my system. I have Windows XP SP3.

Cons: No Thumbnails View but this is not a big deal for me.

Best photoviewer after/like Picasa!
