Batch combining jpg with audio

Hi
This question has been asked before in this forum but it is very old now and even the links posted doesn't work anymore.

Any how as the title suggests, I have a collection of about 300 audio (mp3) files each with an hour of 1hr in length and I need to combine those with the same picture to make a video file so that I can upload those videos in to youtube.

I know I can use Windows Movie Maker for combining, but since there are around 300 files I would like to know whether there is a software that does the same thing in batch without me having to do each individually.

thank you
