Does anybody know how to create a picture package with contact sheet II or know if there is an add-on of ready made conact sheet templates for picture packages?
Depends of version. Either add on or in CS6 contact sheet was added back as option. Picture package was not. Lots of discussion of it in Photoshop forum so a web search should provide workarounds.
I have Web Premium CS6. Contact Sheet was added back but isn't very friendly when it comes to making a pictures package. For instance you want 2 5x7 pictures of the same image done on a 8x11 sheet.
As I said the Picture Package is not an option in CS5 or 6. However lots of hits on subject and some solutions if you do a web search for "photoshop picture package".
