I am working on making a hub for users to view and download spatial data. I'm attempting to edit the icons users will click to direct them to relevant data of interest (e.g. a building icon for users to view building footprint data). I am aware there is an existing library of icons to choose from, but I want to upload my own. Unfortunately I cannot simply upload the image of the icon I want to use, even though that's an option for features like the background image of the site. Instead, I have to provide a url (screenshot provided). I'm unfamiliar with filesharing in this way, can anyone advise on the steps I need to take in order to get the .png image stored on my computer to appear as an icon on the hub? Thank you for any advice.
