Whether you're updating the homepage slideshow, adding a hero image on an interior banner, posting a news photo gallery or uploading a splash video, keeping the imagery on your site fresh is always a good idea. The Resources module makes it easy for you to upload and keep organized. But what's the right size?
This article is meant to outline general recommended guidelines. Every site is unique; however, and exact dimensions for your site's custom treatments and enhancements can be found on your Instructions page in your page tree.

Media terminology
These terms defined below are often used interchangeably, but they are unique elements of an image. Understanding how one affects the other can help you choose a good image for the space you are using and how to properly crop the image or reduce the file size while still keeping the image’s correct proportions.
Aspect Ratio
Dimensions
File Size + Type
- .jpeg
- .jpg
- .png
- .gif
- .heic
Important Note
While .heic files can be uploaded into Resources, they cannot be used or detected as valid images in this format in the Messages module. When uploading files into Resources to be used in the Messages module, it is recommended to first use an .heic to .png or .jpeg conversion tool before uploading.
For more information, see "File types not allowed in Resources."
Resolution
Often web images are displayed best at 72 ppi (pixels per inch) or 144 ppi for digital and higher resolutions such as 300 ppi for printing. Starting with this image which is 800 pixels (width) by 600 pixels (height) it has an aspect ratio of 4:3 and saved at 72 ppi (resolution), a file size of 760 KB.
Now let’s pick a different place for our page that must have the image fit into a space that is 300 wide x 600 high. If we resize the image, it looks like this:
But it doesn’t look as good as the original because the aspect ratio changed. Instead of 4:3 it is now 1:2. So in this case cropping the image is the best option and choosing what portion of the full image we want to use.

-

- Step 2: CROP the height of the image to a minimum of 1080px tall.
Fixed height interior hero images
Header images are great for drawing visitors into a page and leaving an impression. You want to use images that fit your brand, but it's also important to make a selection that fits your site's design, as well. Depending on the style of your site's header banner, some prep work may be necessary to ensure that your content looks good on all devices.
Interior media guidelines:
The proportional relationship between the height and width of a rectangle. Aspect ratio for shapes is represented by x:y, but the actual numbers do not matter as long as the ratio remains the same, just as with image aspect ratio. For example, a rectangle’s aspect ratio is the ratio of it’s long side in relation to its short side.
- Hero treatments: 16:9 aspect ratio
- Featured news & events: 1:1 aspect ratio (Miniumim 800px width & height)
Fixed height banners:
If your site features a hero banner with a fixed height (or max-height), then your images will crop to fit the height set by the design.
Adaptive height banners:
If your site features a hero banner with an adaptive height (or full height), then your images will scale with the screen without cropping.
Hero and background videos
- Video size: 1080P
- Video bitrate: 2500 Kbps
- Frame rate: 30 fps or 24fps
- Key frames: None
- Duration: 15-30 seconds
- Audio: None
- Format: MP4

Thumbnails
Constituent profile thumbnails
In order to add a profile picture to a Constituent's record, you must first upload the image file to your site using File Manager. For more information on how to get started and more precise dimensions, see:Note: This is one of the very few scenarios where File Manager is where these images will be uploaded instead of Resources.
