After a long hiatus from Tom's Definitive Linux Software Roundup, Adam Overa is back with the fourth installment in the series covering Image Apps. This is a showcase of Linux software designed for creating, viewing, editing, and organizing image files.
Part 1: Ubuntu Linux Installation Guide
Part 2: Run Windows XP In Ubuntu Setup Guide
Part 3: Internet Application Roundup
Part 4: Communications Application Roundup
Part 5: Office Application Roundup
There is a longstanding myth that the choice of multimedia applications is sparse in Linux. This article began as a roundup of Multimedia Apps (multimedia being images, audio, and video). We had to split the story not once, but twice, in order to accommodate the number of titles we found. It's safe to say that this myth has been busted.
In this installment, we'll be covering the ways that people interact with images on their computers. The applications in this article run the gamut, from capturing screenshots to creating 3D landscapes from scratch and everything in between. Do you need to replace Windows Live Photo Gallery, Adobe Photoshop, or Maya? No problem. We're covering the best Linux alternatives to popular and ubiquitous image-related applications in Windows.
Do these free Linux alternatives stack up to their proprietary Windows-based counterparts? Luckily, we're including links to download these apps to try them out for yourself. As usual, Windows-based versions are listed here for any cross-platform software. The same applies to Mac OS X as well.
Given the simple nature of most image applications, there are literally tons of them available. The sheer volume of programs made corralling them all into a single story somewhat of a challenge. So, the time we spent with each and descriptions of the various applications had to be shortened to make this piece even possible.
Update: 12/02/10--I have updated this article to include a few key missing applications: gpicview (Page 3), Google Picasa (Page 4), MyPaint (Page 6), and Wings 3D (Page 9).

or Toms Hardware overlooked the three image viewers I use in Debian.
I have used their features

a. feh
feh -D 5 #gives a slideshow, changing every 5 seconds
feg 0t #Uses the thumbnail approach
n and p for next and previous image
b. qiv
-R #so you don't accidently delete a file within qiv ("u" to undelete)
-s #start a slideshow
+/- #zoom
f #full screen
c. xzgv
Yeah give it a try.You can use the Try Ubuntu method or install it instead on a older secondary PC.It's definitely worthwhile and easy.I've been using it on a couple of systems since version 8.04.
