Overview
To display more data in galleries, consider using images to show recognizable identifiers such as Priority or Status of a record. With the use of an image, you can switch between each data option to display a different image. Including tooltips is a great way to describe each image.
Add Image
Go to the Left Nav and search for Image. Drag and drop it in the gallery.

Update the image’s Image property with a switch statement. The switch statement will go through each option and display the corresponding image. There are many sites out there where you can down icons/images. PNG or SVG format is recommended.
Switch(ThisItem.Priority,
‘Priority (Tasks)’.High, HighPriority,
‘Priority (Tasks)’.Normal, NormalPriority,
‘Priority (Tasks)’.Low, LowPriority,
NormalPriority
)

Update the image’s Tooltip property with a switch statement. You can copy the one used from the image property and swap out the images with the appropriate text.
Switch(ThisItem.Priority,
‘Priority (Tasks)’.High, HighPriority,
‘Priority (Tasks)’.Normal, NormalPriority,
‘Priority (Tasks)’.Low, LowPriority,
NormalPriority
)
