I do not really see how Gimp fits in with a web browser extension.
The sort of PS .psd template image in your example is used by replacing / editing or adding layers. Some layers/layer groups might be made non-visible. At the end when you have what you want you can export as a single layer, (flattened) jpeg.
If you want to copy the guides from one image to another, A bit of a hunt around & you might do it with a couple of old Gimp 2.8 scripts, these still work in Gimp 2.10 but can be a little flaky (gat_tools and layer groups)
listguides.scm (goes in the scripts folder) &
gat_tools.py (goes in the plug-ins folder). Scripts attached, unzip pop in
C:\Users\your-name\AppData\Roaming\GIMP\2.10\scripts (or plug-ins)
Would work like this.
Image -> Guides -> List Guides
Keep that info window open and switch to your jpeg image. Open GAT tools
Tools -> Gimp-Atelier and enter the list of Guides. Ok that and the guides are added to your image.
As before, these only exist inside Gimp, Save as a .xcf to keep them, export and you lose them.
