Since computer is not my native language, I don't know how. What I do is click on the title/source of the photo from the forum which takes me to the EBay source where he (the forum poster) found it. Then scrolling down, see other offers. In this case, I use one of the seller's offers, click "other selections" found near the seller's rating, and explore similar stuff.
Edit: It appears the seller does not know about the things in the photos and this is listed as Bf 109 Richtofen JG2, oblivious to the engine change. The thrust line appears that is could be a H-S engine although why anyone would want to do such a conversion.
