  • Images to be used in the IUP template must be formatted to the proper size and resolution. This can easily be done using GIMP, a photo editing software on Windows 7 PCs at IUP.

    Before you start, you will need the image that you want to resize saved somewhere you can easily access.

    1. In GIMP, go to File, Open. Browse to where the file is saved. Double-click to open it.

    2. After the image opens, go to Image, Scale Image. In the window that opens, enter the new Width in pixels. (Use the recommended image widths in the chart in the Size Images for the IUP Templates how to). Then click in the Height box. It will automatically adjust to the correct height. If it does not, check to make sure that the link icon to the right is connected, as shown here: Connected Link Icon - GIMP software. If the icon shows broken links, like this Broken link icon GIMP software, click it to reconnect the links. The connected link will constrain the proportions of the image, so it does not get stretched or distorted.

      Still in the Scale Image window, set the resolution of the image. Click in the X resolution and type 72. Then click in the Y resolution and it will automatically set it to 72. If it does not, check to make sure that the link icon to the right is connected. If not, click it to set the proportion constraints.

    3. Click Scale. The image is now resized. 

    4. Save the image by going to File, Save As. Be sure to give it a different name from the original (adding the width you made the image to the file name is helpful). If it is not already the default, you will need to set the file type to Jpeg by clicking on Select File Type by Extension. Scroll down and click on JPEG image. Click Save.

    5. Another screen will open to set the quality of the image. The higher the quality number (up to 100), generally the larger the file size will be, and the larger the file size, the longer the image will take to load on the page. A setting between 60 and 80 generally provides a good image. Note: You can click Show Preview in Image Window and it will display the file size.

    6. Click Save. To use your image in the CMS you will need to upload it to the library. Read instructions on how to Add an Image to the Library and how to Insert an Image into your page in the How To section.

    Note: If the image needs cropped, this should be done before it is scaled. To crop in GIMP, click the Rectangle Selection Tool in the toolbar. Click and drag to select the portion of the image you wish to retain. You can click and drag again if you are not happy with the selection. When you have what you want selected, go to Image, Crop to Selection. Then proceed to step two to scale the image.
