You cannot specify wildcards as the zip file argument for the zip command because the shell would replace this with multiple file names. Instead you can use a loop to process multiple zip files one by one.

file in *.zip do zip -ur "$file" images done 

or in one line

for file in *.zip ; do zip -ur "$file" images ; done
