In this little post, I'd like to recommend that creators consider using LongText columns to display images via "img scr=" tags. To do so, you need to participate in the "Rich Text Formatting - in Preview Program":

Advantages of this method
Disadvantages
Here's a screenshot from my phone to show how a fairly large (800 x 1192) portrait image displays in a LongText column on my phone.
Good stuff mate! ๐ช Thanks for posting this.
I've found that using the special formatting for LongText columns to be VERY handy for creating a more customized detail view.
FYI: Images also work with Markdown formatting
Thanks for the encouragement. I put together a little template app recently that shows how to take the image data from a single image column and display it automatically as the "main image" of a view, an Image column image, an image in a Show column, and an image in a LongText column.

Each way of displaying images has different advantages and disadvantages. Putting them together in a singe app has helped me get my head around the range of possibilities. I imaging this must be a bit confusing for newbies and, to be honest, I don't think the current AppSheet documentation is particularly helpful.
