Problem with Calling GeneratePageThumbs

[AamirNakhwa]

GeneratePageThumbs is throwing error and GeneratePageThumb working fine. When I dig into this GeneratePageThumb is actually calling GeneratePageThumbs internally. So GeneratePageThumbs expect outputPath which is a string and output files can be multiple. GeneratePageThumbs should get outputDirectoryPath instead of outputFilePath and output file name should be handled within the function.
