Problem ignoring in a view the images inside the .views field body and the minimum number of characters?
The Smart trim module might be helpful. You'll be able to trim units by words or characters on stripped HTML.


  After installing and enabling Smart Trim, you should see a "Smart
  trimmed" option in the format dropdown for your text fields. With
  smart trim, you have control over:
  
  
  The trim length
  Whether the trim length is measured in characters or words
  Appending an optional suffix at the trim point
  Displaying an optional "More" link immediately after the trimmed text
  Stripping out HTML tags from the field
