2.1) Thumb forum code:
shows as thumb, leads to medium
2.2) Small forum code:
shows as small, leads to medium
2.3) Medium forum code
shows as medium, leads to original
2.4) Original forum code
shows as original, leads to original
Personally, I would love to use "show as thumb, lead to original". Right now this is only possible if I copy the thumb code and manually replace "medium" with "original".
