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

    @javabean – Would you be able clarify that a little more for me? Not certain on your meaning there. :( Do you mean about me being the one who wrote this post? The sidebar author section is supposed to be available on ETC posts soon. ^_^

  3. javabean

    Sorry… That’s why i don’t do customer service/how-to(s)

    liferea identified you as the author/creator of this post….but i didn’t find a reference to you being the creator/author on the post(this page) itself

    @javabean – That is ok. ^_^ I figured that was probably what you were talking about earlier. ^_^ Our names will display on the main ETC page as the writers of our posts (just right below the introduction text). ^_^ But once you “open” a post the author sections are missing at the moment. Those are on the way though. ^_^

    You have some great WallPapers here… and I totally love the links to troubleshooting OS issues and Hardware issues… I have got an Acer Aspire 9301 series Laptop which I feel is about due for an upgrade, I have so many external hard drives connected to it through a powered USB Hub with 7 USB ports… my only issue with those are that its got a slow transfer rate and always takes a long time to transfer data from my Laptop to the external drives… the drives are 2.0 when it comes to data transfer, in total I have 7 hard drives connected to this laptop all equaling a total of about 4 and a half Terrabites and then I have a 500 gig in the laptop running window’s 7 Ultimate, I do quite a bit of downloading hence the reason for so many hard drives… Anyways… the point of my being here is basically to compliment your site… it is very helpful on many scales, recently after installing Windows 7 Ultimate I encountered an issue with windows 7… It seems that there was no Quick Launch to put all my short cuts in, so I came to this site looking to see if there was an answer and low and behold I found the answer… and it didn’t take very long either… I was totally overwhelmed by the amount of questions on the page when I found it but after doing a bit of digging I found what I was looking for and then made the applications as directed in the walk through… it was fast and easy and I wanted to send my thanks to everyone who sends in the answers to so many questions… or senarios that plague us on a daily basis… Thank you and thanks to the administrators of this site as well… Thank you for being here and for the creation of this site. Its Freakin’ Awesome!!! :-D
    With Kindest Regards
