I am building website in Tridion 2013 with DD4T and wanted all my multimedia tcm id's in the multi line text field(non rich text) resolved. Does tridion resolves tcm id in text field like rich text?
In SDL Tridion, creating links towards downloadable Binaries (Multimedia Components) in a Rich Text Field of a component, generates a ComponentLink instead of a BinaryLink on the presentation server. These multimedia components being rarely inserted directly on a Page, the ComponentLink does not get resolved on the front end, and your link will not appear on your page.
