Is it possible to give 支持 to things that are NOT images? If so how?

1) go to the users 个人资料
2) either click "give props" underneath their 个人资料 information 或者 go to their wall. 你 can also click on one of the 支持 symbols- many ways lead to rome on this one!
3)click on the grey 支持 symbol (see image) to open all available props
4) write a personal message
5) choose the appropriate 支持 and click "post"

Yes, give 支持 just as 你 would for images, but click one of the options that doesn't say "images"

你 mean give someone a 支持 for a video, comment, article, etc.? Just go to the person's profile, click on "Give Props" (left-hand side of the 个人资料 page, in the "about me" section), then click on the type of 支持 you'd like to give. 你 can also add a comment, explaining what the 支持 is for, at the same time.
