In order to keep a clean design, CrystalXP.net's team would like that every thumbnail that'll be displayed in the gallery is based on the same model.

You'll have to open this file with a graphic image editing program. Examples are Photoshop, Paint Shop Pro and the Gimp. However, the .psd file is originally made for Photoshop. If you want to open it in any other image editing program you might have to install plugins.

Thank you very mush  

No problem. Have you already found out how it works?
