Help with finding components I just used

If the file was opened recently, the image may still be in your Recent History folder.

File > Open Recent > 

If it was a while back, use your computer's search & sort functions to find it.

Open your operating system's file manager -- Win File Explorer or Mac Finder.

Perform a file search for Flower_Pattern.png.

Hope that helps.
