http://demo.wagn.org/wagn/footype+*tform has:
[[+Picture|{{+Picture}}]] and this is apparently what's causing the problem (uploading through the above seems to be fine).
Go to http://demo.wagn.org/wagn/and_yet_more_image_testing and:
You get redirected to an offer to create "and yet more image testing+Picture" (i.e., it will not have been created).
If it works (it worked once for me), just create a new card and set it to type footype, Create it, then go to 1. above. In case it's something particular to the images i'm using, you can download http://s3.amazonaws.com/demo.wagn.org/card_images/16/Bregenz_Media1.jpg
If you do the upload from the create page — http://demo.wagn.org/wagn/upload_during_create_testing?type=footype — then you don't get redirected, but the file is still not uploaded.
When this is fixed, can change http://earlysteps.wagn.org/wagn/Poster+*tform to show medium image linked to picture's card.

This seems like a really old ticket that may not apply in the same way. At a minimum we should be talking about *structure rules now, right?
Yeah, *tform is two lingo revisions ago and the name of the trunk change too :-) now it's http://earlysteps.wagn.org/Poster_Presentation+*type+*structure
