Hey guys how do i can import image sequence ?

i have three files dragon1.png dragon2.png dragon3.png - just once the dialog show up and work.

now i want to import a image sequence with 19 frames. nothing happen.
im using MacOS

If the dialog asking you about it doesn’t show up, that means you’ve checked the “don’t ask me again” checkbox while loading an animation before. to bring the dialog back, go to Edit>Preferences and try to find a setting about loading animations and image sequences
