What is the correct way to include HTML for images in a formula text field?

In a formula text field within NetSuite, the correct way to include HTML for images is by creating an HTML image tag that correctly interprets the URL using single quotes. This means that the URL needs to be defined within an HTML tag, and the URL string should be surrounded by single quotes for proper formatting.

For example, when constructing an image tag in a formula, it would generally look like this: <img src='URL' alt='description'>. Surrounding the URL with single quotes ensures that the formula processes the string accurately, allowing the browser to correctly interpret the HTML for displaying images.

Using single quotes is critical because it differentiates between the HTML syntax and the string representation within the context of the formula. This ensures that the formula functions as intended when rendered in the NetSuite environment.

Other options may include various element characteristics, but they do not accurately reflect the proper syntax and methodology for including images in a formula text field specifically in the context of HTML formatting.
