[support] how to change a content type format

[Marty Landman]

I am doing some maintenance on a site and the author is unavailable 
for any questions. Being pretty new to Drupal I'm able to track 
things so far but no farther. In this case there is a view with a 
display that shows a particular field listed as

Content: Box shot  - front_thumb image linked to node

Need to locate those formats and either edit the existing one or 
create a new one. Hoping the format includes hard-coded image height 
& width attributes cuz that's what needs to be changed, and I checked 
all the themes listed for this view display and nothing is in there 
so hoping, thinking it's got to be in the format, but where are the 
formats? Also looked at the content types and list of fields, not there either.

Hope this is coherent.
