Align visible layers in a GIMP booth composite
Use the image-level alignment command when several visible layers need one common edge.
A hand-built strip composite can drift when separate portrait layers are moved by eye. GIMP offers an image-level command for aligning visible layers. Use it only after deciding what should line up, and duplicate the document first because automatic alignment may move several elements together.
Prepare the stack
Show only the layers that belong in the composite and hide reference scans or notes. Duplicate the image before using a batch alignment command. Check the layer boundaries in the Layers dock so you know which objects the command will affect.

Choose the alignment
Open the Image menu and choose Align Visible Layers. Select the edge or centre that should anchor the visible content. A shared left edge can suit a vertical strip; centre alignment can help when frames have different transparent margins.

Inspect every panel
Compare the face positions and actual image bounds, not just layer boxes. Undo if the command aligns transparent padding rather than the visual content. Move individual layers manually when subjects need different spacing, then export a proof.
