I'd love to, but I don't know yet how to use the libpurple functions.

I just want to know how I can change an account's buddy icon. I saw
that Pidgin creates a *.png file with an md5 hash as file name. I want
to set a picture in the Plugin, and the plugin calls the corresponding
libpurple function to change that picture.

In buddyicon.h, I found the following function:

purple_buddy_icons_set_for_user(PurpleAccount *account, const char *username,
                                void *icon_data, size_t icon_len,
                                const char *checksum);

Can anyone pls give me an example so I can understand how it's made? I
don't know what *account is, I thought it was like
"mymsnaccount at hotmail.com", but why the username?

Thank you!
