Link to images(thumb) in a (block)view to the image(original) in another (page)view
In your block view, if the "Link image to " option doesn't give you what you need for the thumbnail image field, you can build your own link using "Rewrite Results". You would do something like this:


Add content:path or nid to your view, and exclude from display
Make sure content:path or nid is first in you list of fields
For the thumbnail image field, enable "Output this field as a link " under Rewrite Results
use the token for nid or content:path (i.e. [path]) to construct the link you need


Note: if you use content:path, you will probably want to enable "Use absolute path" for it's field settings, even though it is excluded from display.
