How can I use Photoshop to create an animation? Now I have three modified images?

Set the order of your images in Photoshop to layer 1, Layer 2, and Layer 3 (new, copy and paste the image), and then bring up the animation in the window, the triangle on the right-create a frame from the layer, set the image switching time (right-click), and save the file as the WEB format-ctrl + alt + shift + s. That's all.

How can I use photoshop to combine three jpg images into a dynamic GIF image?

First, we will tell you that the operation methods for different PS versions are basically the same.
The procedure is as follows:
1. Open the three images to be merged.
2. Drag any two images to one of them.
In this case, select the tool (shortcut key V) in the toolbar, press Ctrl, and click the image to be dragged. Do not release the mouse and move the mouse to the image to be dragged, then, let go of the mouse and drag the picture to the other image, and drag the third image together.
3. When the three images are all in one, three layers appear on the layer panel. Then open the animation panel (in the window menu). The animation panel has only one frame, and click the bottom-down button at the bottom of the animation panel to copy the frame.
4. Copy the two frames and click the first frame to return to the layer panel. Remove the eyes in front of the two picture layers so that only one image is displayed. Similarly, click the second and third frames so that each frame displays three images that cannot be accessed.
5. Click the first frame, hold down the top key, and then click the last frame, that is, the third frame. After selecting all frames, click the inverted triangle on the right of the time at the bottom of any frame and select the conversion time.
6. After setting the time, you can click the play button in the bottom row to see the effect.

Save:
After the effect is reached, click "file" in the upper left corner and select "storage as web and device format.
In the upper-right corner of the dialog box, select the file format as gif.
Click the "Storage" button in the bottom row to generate gif dynamic images.

Try it with pure hands!
