"Imort selection" - anim editor - what does it do?

I have looked in the help files, done searches here but can't find info on this. Nothing happens when I "tick" it.
Any info appreciated.

When it is checked you can use the Select button to select only a portion of the picture to be imported.

I see. Thanks. :)

I thought I could select a bunch of images and have them all imported, one frame each, in one go. Would have been nifty though. :)

There is a way to format an image file to import multiple frames at once. Check in the manual, I'm pretty sure it's in there, that or the help file.

Make it a GIF.

Yes it has something to do with the naming convention of your files. If you import sprite001.bmp and the same folder includes sprite002.bmp, sprite003.bmp etc.. then MMF will ask you if you wish to import the whole sequence of files as an animation.
