If you mean a picture as the fill for your text, rather than the shape containing the text, I do not believe that has been available since Word 2007 without Add-Ins. Here is the menu for changing text when in Word 2007 compatibility mode.
If you save your document in Word 2007 Compatibility format, you would have access to the older WordArt controls and menus. A macro to do this is at the bottom of this answer.
You can get access to the classic WordArt through a macro prepared by Greg Maxey.

Greg's macro gives you access to the traditional controls in a WordArt tab.
Greg's macro and a menu of legacy WordArt is available in my WordArt Add-In.
In recent versions of Word, though, using the Picture fill command only changes the first letter of your WordArt. If you have Word 2016 or earlier, they are more powerful and can change the entire WordArt.
Here is a macro to change the current document to Word 2007 Compatibility mode. Using it changes your Insert > WordArt command to the old menu.
