subfigure in llncs class

Question

When I am using \usepackage{subfigure} with \documentclass{report} it is working fine and I am able to use it but if I use \usepackage{subfigure} with \documentclass{llncs} then the file is not compiled and gave me output as 0 error ... 0 Page(s) with Couldn't file input index file file_name and file_name.idx

Can someone help me what should I do? I want to display two figures side by side.

package subfigure is obsolete, use subfig instead. You can also try package floatrow. You'll get the documentation with running texdoc subfig or texdoc floatrow
