Are you looking for an easy way to create custom sized thumbnail images for use in blog posts, photo albums, and more? Whether is it a single image or a CD full, Simple Image Resizer is the right app to get the job done for you.

To add the new PPA for Simple Image Resizer open the Ubuntu Software Center, go to the Edit Menu, and select Software Sources. Access the Other Software Tab in the Software Sources Window and add the first of the PPAs shown below (outlined in red). The second PPA will be automatically added to your system.

Once you have the new PPAs set up, go back to the Ubuntu Software Center and click on the PPA listing for Rafael Sachetto on the left (highlighted with red in the image). The listing for Simple Image Resizer will be right at the top…click Install to add the program to your system.

After the installation is complete you can find Simple Image Resizer listed as Sir in the Graphics sub-menu.

When you open Simple Image Resizer you will need to browse for the directory containing the images you want to work with, select a destination folder, choose a target format and prefix, enter the desired pixel size for converted images, and set the quality level. Convert your image(s) when ready…

Note: You will need to determine the image size that best suits your needs before-hand.

For our example we chose to convert a single image. A quick check shows our new “thumbnailed” image looking very nice.

Simple Image Resizer can convert “into and from” the following image formats:

  • .jpeg, .png, .bmp, .gif, .xpm, .pgm, .pbm, and .ppm
