Embedded Media Field. Maintainers: aaron (Aaron Winborn) and Alex UA (Alex Urevick-Ackelsberg) This extensible module will create fields for content types that can be used to display video, image, and audio files from various third party providers.
When entering the content, the user will simply paste the URL or embed code from the third party, and the module will automatically determine which content provider is being used. When displaying the content, the proper embedding format will be used. The module is only an engine, and requires a supported module to function. These include 'Embedded Image Field', 'Embedded Video Field' and 'Embedded Audio Field'.
Gallery formatter. Image Delta Formatter. Image URL Formatter. This module add a url formatter for image field.
Then you can output image url directly. Most of the code, maybe more than 90%, is just copy from the drupal core. I think it is stable enough.
