Well, I'd post concept art for the various wonders and SW that are still needed, but I can't even find any half-decent in-game SCREENSHOTS anywhere on the net.... I could try a description, if I can remember/know of something that would work.
Here's the list of wonders:
The Great Gospel (FF I&II) Perhaps some religious-looking tome for the icons and a group of angels for the splash....
Garden (FF VIII) You know, where Squall & co trained at... I COULD get a couple of screenshots for you by tomorrow (HOORAY for FF VIII PC!)
Eidolon Wall (FF IX) Basically a wall with paintings of the different summoned creatures in FF IX (also has Princess Garnet's REAL name)
Cavern of the Stolen Fayth (FF X) The cave where you find Yojimbo in FF X
Trial By Wind (FFXI) Cape Terrigan from FF XI, where you get Garuda.
In addition, I still don't have any decent graphics for the following Great and Small wonders for all civs:
Zidane's Voyage (need a pic or two of the Blue Narcissus)
The White Materia (currently uses the SDI graphics) I may be able to hack together something from pics that Chris85 got for me for this one.....
also, here's the pedia text:
