Hungry ... where is your signature, where is the forum and where is QQ? QQ can't be used unless there are some small Tencent icons. You can add it to the forum if you have permission. There is a specific operation process, which is very simple. Just pick a picture.

Regarding the second one, I can only use ps. For example, to make a GIF with three pictures changing repeatedly, you can first make nearly 10 blank pictures, assuming that three source pictures are A, B and C, the first blank picture is placed in A, the fourth blank picture is placed in B, the seventh picture is placed in C, and then there are three blank pictures and a * * * ten. Then set the time from A to B, the time from B to C, and the time from C to the fourth page, and select cycle. Then preview to see the effect, PS will automatically change the filter. Not enough to supplement. The extra picture in the middle of the two original pictures can be biased to A or B through the slider below. I write very hard. Although there is no specific operation, it is not difficult to operate in principle.

If you find it difficult to set yourself up, recommend a simple software, GifCreator, which combines multiple pictures into gif animation.
