If you're looking for a plainly simple image viewer, you've come to the right place: here's VJPEG, a photo viewer that displays images right on your desktop.
After installing it, VJPEG takes over the native Windows image viewer and opens all JPG, BMP and GIF files on the desktop. Images are opened as is, in other words, without any additional frames, windows or interface: just the image itself.
So without any interface, how do you manage images in VJPEG? Easy: with mouse and keyboard combinations. VJPEG lets you drag and move images around the desktop with the mouse and close them with a right click. If you want to resize them (just for viewing purposes, no actual size changes are applied) stick the image to the left screen edge and drag it. Other tools available in VJPEG are rotating, zooming in and out, adjusting levels and even sending by email.
VJPEG is a good solution for those who want just a simple photo viewer without all the bells and whistles of other programs. I miss having some kind of documentation though, as well as having a nicer icon for my graphic files, which lose their standard icon as soon as they're associated with VJPEG. Other extra options, like being able to minimize or tile images, would be nice too.
VJPEG replaces Windows default image viewer with a dead simple app that displays pictures right on the desktop and lets you drag and resize them with the mouse.
