I'm trying to export some images of a photoshop design and this is how I usually do it:
- select the layer you want.
- command + left click the thumbnail to create a marquee around the layer
- copy it (command + c)
- Create a new file (command + n). this will create a file with the exact dimensions as the layer
- paste in the copied layer. (command + v)
- save for web
For certain layers I get stuck on number 4 where photoshop doesn't know that I copied something onto the clipboard so the right dimensions aren't displayed. plus pasting doesn't work because for some reason it was never copied. I don't know if certain layers cannot be copied simply by pressing command + c?
