javascript - How to change Facebook link appearance on wall? -

-

i've got website creator - can make own character.

character generated in dynamic way via js. after registration, character saved on server. when user wants check character, can use link e-mail or find in gallery. when user using link, i'm taking data url, getting data server via ajax , showing user his/her character.

problem started when wanted implement facebook's , share buttons. whole content generated in dynamic way , have access client-side of project.

share button not problem anymore because i'm using feed dialog can use dynamic data.

problem button. because of way how website works, don't have webpages every character different open graph tags on server-side.

when new character shown in gallery, i'm changing data-href atribute button , calling fb.xfbml.parse(); refresh data in button. static thing generated character image (every character has it's own image saved on server) i'm using link image button. button works fine, number of likes shown in correct way.

but when clicking button, on his/her facebook wall data shown this:

user xxx likes link: www.example.com/data/gallery/xxxxxxxxxxxxxxxxx.png

is there way (with fb js sdk or fb app options / open graph story) change data shown on wall? example:

user likes: (title/name of facebook app)

or looking less ugly?

if not, if there way change open graph meta tags current character?
