How can i reverse Gif image with out affecting animation of the image and save it. I used Flip Tool and reversed image then after save it. Then i lost the animation effect of the image.
Go to the Image -> Transform -> Flip Horizontally.
I had 2 layers and after flipping, the animation worked as expected. If you are having problem, could you upload your GIF somewhere and paste the link here so I could have a look at it?
File > Open as Layers - then > Image > Transform > Flip Horizontally - then > File > Export As
In the Export As dialogue box file name field give the file a .gif extension.
In the Export As Gif dialogue box select the As Animation tick box
Then select Export
I prefer to do this using an online tool like https://gifreverse.com. It's not directly in GIMP but for me it's faster because the process requires export/import and multiple menus when done natively.
