how to fit an image to a 3d layer from banner template

hello

I bought an e-book banner and it has a 3D ebook layer and i want to fit there an image,
i’m using photoshop cs5 can anyone help me ?
thank you

There is no help file provided?

Probably there is used “smart object” with design (which is transformed to perspective view, but keeps the original size and aspect of design inside), you have to double click this layer thumbnail preview and then fit your layout into opened .psb file, save it and exit, then your layout should be updated in book template.

Hope it helps :slightly_smiling:
