Word to the wise:
avoid BrotherSoft site downloads like the proverbial plague: their *.exe installer files are bundled with tons of self-serving advertising and other nefarious nuisances.

Here is a safer source for diminutive LittleViewer: (21k, compressed with Yoda crypter)
http://download.freewarefiles.com/files/LittleViewer.zip

Besides the above warning, I concur with Thomas about LittleViewer being perhaps a trifle too minimalistic to navigate folders in comfort, regardless of its appealing minuscule footprint.

Keeping the tiny league in mind, a more appropriate viewer choice might be:
MycView (40k, UPX-compressed)

BTW, the FreewareFiles repository offers a nifty "Sort by File Sizes" function which I would dearly love to see implemented on PCF...;-)

The website www.brisksoft.com is down, but it can still be seen via Google's cache: http://tinyurl.com/2dposn - it's in English, but minimalistic and hardly worth visiting.
The file itself is available at external download sites, e.g.
http://www.brothersoft.com/littleviewer-download-40947.html
The viewer is totally minimalistic - no wonder at 20 k size... The biggest problem about is, you can't locate files in an external file explorer and then open them with this viewer. Instead, it always starts with a folder tree view of the desktop, from where you'll have to go on a "clicking journey" to locate the image folder you want to view. Overall, unless you're a complete tiny software freak, go get something a few kilobytes bigger but more comfortable...

The download link takes you to a Russian-language website. If you run out and grab yourself a Russian translator, you'll know which link to click to download the file!
