For bikes that have half length / short horizontal dropouts there is usually a lot of extra casting that can be machined to extend the dropout to allow for adequate adjustment but I do not see your bike as having this problem.
When I shortened the chain the first time, the axle was in the position you see in the pics. So I added a full link. Even with the axle to the back of the drops, the full link gave the chain too much slack.
