Create a dictionary mapping the name to the image object. For example:
# Create all your images first
# Map a name to the image object
self.catdict = {'all' : self.all, 'installed' : self.installed, .......}
# Loop over the image names and do your stuff
for item in self.catdict.keys():
print item
self.categorytable.insert(END, item)
self.categorytable.cellconfigure("end,0",image=self.catDict.get(item))
