As Yeti already pointed out, build a struct to hold it all, alloc it,
pass pointer to struct (and don't forget to free when done ;-)

Or, if you are sure that there's only one struct in use at a time, use a
static (but this is a dirty technique which will haunt you at night,
believe me).

A quick and dirty thing I use to do (when the complexity of doing stock
item things scares me -- I'm easily scared by complexity, you know) is
something like:

 | #define NRPICS 4
 | typedef enum {
 |   sheep,
 |   cow,
 |   petunia,
 |   alien
 | } mypic;
 | 
 | static GdkPixbuf *getpix(mypic pic)
 | {
 |   /* Returns pixbuf corresponding to whohas */
 |   static GdkPixbuf *pix[NRPICS];
 |   static char *fname[NRPICS] = {
 |     "/path/to/sheep.png",
 |     "/path/to/cow.png",
 |     "/path/to/petunia.png",
 |     "/path/to/alien.png",
 |   };
 |   if(pic<0 || pic>alien) pic = alien;
 |   if(!pix[pic]) /* not yet realized */
 |     pix[pic] = gdk_pixbuf_new_from_file(fname[pic], NULL);
 |   return pix[pic];
 | }

Modify to own taste.

Of course, you can get all fancy and read the list of files from a
config file ant that -- but from some point on you might be better off
reading up about all this stock stuff (which is far more
theme-friendly), for example here:
