Resizing Images
If you have an image to put on a page on the Rebel Toolkit, you may need to resize it in order to get it to display at the correct size on the page. This involves reducing the resolution of the image, ie reducing the number of pixels in the width and height. You do this on your computer before uploading it to the Rebel Toolkit. You can see the dimensions of an image by hovering your mouse over the name in Windows Explorer. For an image on a web page, right-click and select View Image Info (in Firefox), select Inspect and hover over the image element (in Chrome). In most cases you will want an image between 200 and 600 pixels across.
It is a good idea to make a copy of the image and resize the copy.
There are numerous tutorials available on how to resize images, and a selection is listed below. Note that many of the tutorials are trying to get you to download a piece of software or to use a particular web site. You do not need to install any new software or to use a web site or online service. Whether you use Windows, a Macintosh or Linux, your computer already has the software you need to resize images. The list below only covers Windows. Feel free to add suggestions for Macintoshes if that is what you use. Linux is more tricky, and you may actually want to install some software.
