…hat use base64 data encoding. This limitation arises from ChatPromptParser.cs only calling the ImageContent constructor requiring a Uri which results in an InvalidOperationException. The proposed fix involves a simple check to determine if the content starts with "data:", and if it does the ImageContent constructor that accepts a dataUri is utilized instead.

Motivation and Context
At present, including images in prompt templates using base64 data encoding is not possible. This limitation is due to
ChatPromptParser.cs
exclusively calling theImageContent
constructor that requires a URI, which leads to anInvalidOperationException
. The change required is straightforward and the limitation has been discussed before, for example here. Closes #7150.Description
The proposed trivial fix involves a simple check to determine if the content starts with
data:
, and if it does theImageContent
constructor that accepts adataUri
is utilized instead.Contribution Checklist
