AcetoneISO is a graphical application written in Qt4 which lets you mount CD/DVD images easily. The formats supported are ISO, NRG, MDF, BIN and IMG. It does not come in Debian's repositories, but I will show you how to easily install, run and start to use it.

In this guide I will show how to create CD/DVD ISO images in Ubuntu using four easy methods.

While you might associate working with images with big graphical programs like GIMP or Photoshop, ImageMagick is an entirely different animal. It is a suite of command-line programs for converting and manipulating images.

Furius ISO Mount is a tool that lets you mount and unmount ISO images on your desktop, calculate the checksums (MD5 and SHA1) of the ISO images, and burn them onto a CD or DVD (using external programs like Brasero or Nautilus). It comes with a graphical user interface and is extremely easy to use. This guide shows how to install it on an Ubuntu 8.04 desktop.

Usually when we talk about programs for editing images we think to graphic programs such as The Gimp or photoshop, but they are not the only alternative.

I’m a sucker for a cool space wallpaper, and judging by the images I find online, so are many of you. Creating a cool space scene can be done in a few minutes once you’ve got the basic method down, and Gimp provides several ways to go about adding random elements to keep things interesting.

The composite command from ImageMagick provides an easy way to watermark images. Without too much work you can write a script to do batch processing of your images. This way you can watermark a whole directory of images at once.

Like all Linux distributions, Ubuntu 10.10, aka, Maverick Meerkat, the latest version of the popular Linux distribution, ships with a firewall installed. The firewall is actually embedded in the kernel. In Ubuntu, the firewall’s original command line interface has been replaced by ufw, a more user-friendly command line script.
