Hi there I'm trying to export all of the layers in my `.psd` to `.pngs`/`.jpegs` and I am having trouble exporting them so that the sizes of the individual `.pngs` are the size of the image they contain. 

I have seen this [thread](https://graphicdesign.stackexchange.com/questions/1961/export-photoshop-layers-to-individual-png-files-batch-process) which has a script that almost does this but since I'm a new user here I can't comment on it...if the creator of that script (Johannes) could respond i would be very grateful.
