Animation Quickie

So first thing is to bring up the animation menu.

To do that, click on the Window tab located at the top right of the bar, when selected, scroll down and click on Timeline (The extensions are Alphabetically ordered for convince)

A large new box will appear at the bottom of the page

 The current box listed is one of a Smart-object manipulator, for this tutorial I will be showing frames, as such, click on the 3 boxes in the bottom left corner of the Timeline box.

(Print-screen errors regarding going step-by-step visually, bear with the comments)

You'll be enabled with a smaller tab that will show you have but one frame, click on the settings page at the top right of the box (Labeled 1) that will apply all kinds of settings, you'll want to be sure for novice type editing that "New layers visible in all frames" is not ticked, and amongst the list is New Frame, when ticked you can create multiple frames and make tweaks within each of them, be it moving an object or making something suddenly appear.

Label 2 is the number under the box is the time before it ticks over to a new frame, simply click the arrow to adjust, it's preferable to select other so you can be specific with the time ratio. Under that itself it should say once, in regard to a loop, you'll probably want to change that to Forever

When you've played around and are satisfied with your result, to save as a GIF.

Go to, File and scroll down to Export, a new selection of items will appear, and you'll want to select 'Save for Web (Legacy), let the file load in the incoming box, apply the numbers and selections up above for best probably quality before clicking save.

When saving, remember to save it as a GIF.
