How to develop website from large PSD templates

I have watched a plugin review recently on Youtube
(Divine Elemente: WordPress Theme from your Photoshop Design)
Is anyone used it? Does it support large template sizes (85Mb)?

No I never used that, but an 85mb template is way too big to go online.

I have searched for it and has some good review but personally I do not support any automated tool for conversion of PSDs as they have some drawbacks. I prefer to choose manual submissions.
