add edited gif to your background image

open the image that you downloaded first and then add your revised gif to ityou will most likely have to adjust your gif to where you want it to be placedto do this you will have to link all of your frames together, leaving out the downloaded image.hold shift and click on the box that appears next to the eye in your layer box. (holding shift is just a shortcut so that you don't have to click them all individually)once a chain has appeared next to all the eyes, scroll down the layer box and click on the chain where your downloaded image is so you don't move it with the other frames of the gifuse the move tool (four arrows in the tool box or press m) to drag the gif where you want it and afterwards to unlink all the frames hold shift and click on one of boxes twice and then unlink the remaining frame.the next step is the most tedious out of the steps, unless you're able to find a way to do it quickly.if you have a gif with very few frames then you are in luck because for this step you will have to merge the layers of each frame to a duplicate of your image*continuously repeat this step until all layers are completed1. in the layer box, click on your image and then click on the the double box icon below it:*for a more efficient way of doing this, once it is duplicated, drag the copy of the image above each frame of the gif (and then do what # 2 says every frame merged) for example:2. click on the layer of a gif above the duplicated image and then go to the main window of gimp and select the layers tab and click on "merge down"you will have to do this for each frame, duplicate the image, merge down the frame, duplicate merge, duplicate merge, etc. tl;dr: duplicate stock image for each frame and merge each frame to it's own imageif this step has been done correctly, your layer box will look something like this:all frames should look like they have a background behind them on the layer box previewafter that is done your gif is pretty much finished. to check if you did it correct go to filters, animation, and then playback. there should be no glitches or anything, it should be just your gif over the background.
