All uploaded media assets can easily be replaced for different media. This may be useful if you use a background or anything else that you need to be changed for all banners in the banner set or for everywhere it's used, which is depending on whether the asset is set to be a Shared asset or not.
☝️ Please be aware of that when replacing the media, everywhere it's placed, the media will be exchanged. But don't be too worried, you will get a warning if you try to replace your logo to a different image across all banner sets!
1. Hover your mouse over the media asset in the library and then click on the wrench icon that appears alternatively right click on the media asset and click Edit.
2. You will now see the image settings, simply click on Replace and browse to your new media or just drag and drop the file you want to replace the concurrent media with. Please be aware of that when replacing the media, everywhere it's placed, the media will be exchanged if the shared option is active.
