Switch Layer is a QGIS plugin that mutates the visibility of layers one by one with a slider from a selected Group.
Switch the layers' visibility without a hassle if you are comparing multiple temporal images.
You can either search and install from the QGIS menu Plugins > Manage and Install Plugins > Search
or can download the zip from this repository and install from the zip file using the QGIS menu Plugins > Manage and Install Plugins > Install from ZIP.
Make a group from the layers you want to compare, like a time series. Open/refresh the plugin, select the group name, and finally move the slider.
