Both CU Denver and CU Anschutz have digital asset systems to provide quality images that a university approved.
You can also use free stock images. Here are some of our recommendations:
Sitefinity accepts the following file types .gif, .jpg, .jpeg, .png, .bmp, and .svg
Now that you have your images, the next step is to optimize them! When we optimize images, we're trying to make the image as small as possible, while sacrificing as little image quality as possible. There are three main tools we currently recommend. You may like one more than the other depending on whether or not you have to optimize many images (batch) or just a few.
The following image sizes represent the maximum size an image should be in various contexts for optimum page load times. Users should not exceed the maximum of either recommended height or width. In some cases, an image orientation is also recommended.
Images smaller than the recommended size will load faster, but the image fidelity and/or layout may be compromised with image pixelation or the image may not display at full width of the widget. These height and width values represent the largest possible display size of each on the page.
So, you have your high quality images in the right size. Now you it's time to upload right? Not quite. Before uploading your image into Sitefinity, you need to rename the image file to something that describes the image. When the file is named correctly, it will autofill the image title and alternative (alt) text. This is mainly for accessibility and can help increase your search engine optimization (SEO).
What's a correct way to name a file? Look at the image below.
Originally, the image was named IMG_001. Instead of uploading with that file name, you can change the name to be more title and alt text friendly, like "Golden retriever puppy laying in the grass."
You done all the work to name, size, and optimize your image(s). Now it's time to upload them:
Libraries are like folders for your images and should be used to organize your images. Learn more about libraries.
Ask yourself: Do I really need to use this image?
Many times, simple text is better. If the image doesn't help convey your message, you may not want it taking up space (and load time) on your page. You may think the image looks nice, but most people don't come to your site to admire your artistic aptitude. People come to your site to accomplish a task or quickly gather information. Get to the point.
