Image Optimisation

Images are key to great communication on your Vibe channel. Remember the saying that "A picture paints a thousand words". This article guides users on preparing, uploading, and optimising images for Vibe.fyi digital signage, including recommended file types, colour settings, dimensions, design margins, text and graphics guidelines, image compression, and handling cached images.

Why it matters: Following these best practices ensures images are clear, legible, and visually effective across all screen sizes and orientations, reduces file sizes for faster loading, prevents display issues, and avoids outdated content being shown, maintaining a consistent and professional digital signage experience.

File type	JPG, JPEG, PNG or GIF
Colour mode	RGB
Landscape artwork	1920 × 1080 px, 16:9
Portrait artwork	1080 × 1920 px, 9:16
Filenames	Letters, numbers, hyphens and underscores only
File size	Compress before uploading

Adding an Image to a Slide

Within the Vibe Portal, create or edit an existing slide.
In the Content Source dropdown, choose Web Portal.
Add an image using one of the following methods:

Drag and drop the image into the Upload field, or
Click Add Content, or
Upload the image through the Image Manager

Quality & Dimensions

Content Artwork

Acceptable file formats are: jpg, jpeg, png, gif
Create the image at the full pixel dimensions required by the display.

Note: If you use a thumbnail sized image, then you will see a thumbnail sized image on screen. It will either be too small to see, or very blurry.

RGB Colour mode

The Image Manager supports image filenames using alpha-numeric characters and the underscore/hyphen symbols. Before you attempt to upload a new image, remove any unsupported characters (e.g. & ampersands, ( ) brackets, + plus etc).

Background Images

Dimensions will vary according to the resolution and default orientation of your screen/device. If you have a combination of portrait and landscape displays, try creating a 1920 x 1920 px image that works best on both or apply a specific background.

A standard TV Screen display, will be one of the following:

Landscape Screen Size: 1920 x 1080 pixels / 16:9 ratio
Portrait TV Screen Size: 1080 x 1920 pixels / 9:16 ratio

Layout and Design

Make sure that you design for legibility and readability and consider that text is large enough, isn’t crowded and colour choices provide good contrast.
Establish a ‘Safe Area’ around the edges of your design to allow for any mandatory logos or information bars that are already established in other slides.
Use simple, clean graphics and photography
Where possible, add editable text and logos through a Vibe Template rather than embedding them in an image. IE: Avoid words and logos in images.
Make sure any images that you add will enhance the written message, not distract from it!

Guidelines for a 'Safe Area'

Compression

For the best results, we highly recommend compressing images before uploading them. Compressing the images will give you a big reduction in file size without losing quality.

All files used to create your slides (i.e. images/spreadsheets/etc) are downloaded to your workplace digital signage media player(s) and stored locally (until the slide is updated or deleted). Try to optimise and compress your files as much as possible to reduce data usage.

Try a free online compression tools to prepare your images, such as: TinyPNG* https://tinypng.com

Image Caching (Cloudflare)

Vibe.fyi uses Cloudflare caching to optimise image delivery performance across all screens and devices. This means that once an image is uploaded and delivered through our network, it may be cached (stored temporarily) by Cloudflare for faster loading.

Best practice for replacing existing images

If you upload a new version of an image with the same file name, Cloudflare may continue to serve the cached (older) version for up to 24 hours. This can result in the new image not appearing immediately, even after multiple browser refreshes.

When possible: Upload the updated image with a new file name (e.g. banner-v2.jpg instead of banner.jpg).
If you must keep the same file name:
1. Allow up to 24 hours for the cache to update automatically.
2. If the new version still isn’t appearing after 24 hours, submit a support request asking our team to force a cache refresh.

For urgent updates, renaming the file is the fastest way to ensure the new image is displayed immediately.

Troubleshooting Cache Delays

If your new image doesn’t appear after uploading:

Try a hard refresh in your browser (Ctrl + F5 on Windows / Cmd + Shift + R on Mac).
Clear your browser cache or test the image in a private/incognito window.
Check the image URL directly — if the old image still shows, Cloudflare is likely still serving a cached version.
Wait 24 hours, then if needed, contact Vibe Support to perform a manual cache purge.

FAQ

Troubleshooting new images not appearing?

Perform a hard refresh:
- Windows: Ctrl + F5
- Mac: Cmd + Shift + R
Clear your browser cache or use an incognito/private window.
Check the image URL directly; if the old image shows, Cloudflare may still be caching.
If the new image doesn’t appear after 24 hours, contact Vibe Support for a manual cache refresh.

My slide is not showing the updated image

Vibe.fyi uses Cloudflare caching for faster image delivery.
When uploading a new version with the same filename, Cloudflare may serve the cached older image for up to 24 hours.

Best practice:

Upload the image with a new filename (e.g., Name_v2.jpg) for immediate updates.
If keeping the same filename, allow 24 hours for cache refresh, or submit a support request for a manual purge.
