A few things to be aware:
Using a for loop here limits to files that do not have spaces, if any file matched by find contains spaces the script would introduce a behavior you do not want. And by the way, find will process any directory tree recursively.

find . -name "folder.jpg" will not be limited to only files but to directories that contains that name as well.

Here's another untested version that might process any files named folder.jpeg or folder.jpg in any directory starting in the current one.
If you like what echo produces, comment it and uncomment the convert.
As an example it does change the name with one of your new names suggestions.

Code:
#!/bin/bash

find . -type f -name "folder.jp*g" | while read f
do
  path="${f%/*}"
  extension="${f##*.}"
  echo "$f -> ${path}/album_art_small.${extension}"
  # convert "$f" -resize 200x200\!  "${path}"/album_art_small."${extension}"
done
