I've maxed the extent to which I can use the QuickBase icons, and now I want to be able to use other icons, so I've added an Icons table to my QB Admin app, which I want upload icons into and refer to...
And rather than creating an image preview field, then referencing that in your button, you can reference the direct URL, which might speed things up a little.
Just modify the field properties of your file attachment field to be accessible without logging in, and now that file attachment is a permanent link for anybody to see/use
Then you copy the URL into your 'a'frame. Add your own action URL to the href, and size it as you'd like.
If you want to just display that image, and always have it be static, using the URL is best.
If you want the image to change and be dynamic based on some other field, you can make a conditional statement to display different images.
But to be able to use the image in a completely different application that doesn't have a relationship, you will want to stick to the URL from the file attachment
