Jpeg

How can I save all my pictures in one go,
as Jpeg where some of them are a 24bit image things
or do I need to edit each and every one in turn?

Get hold of Irfanview (google it) and do a batch conversion.

If it's the first time you might want to set the output directory to a new folder so that you don't have any file overwritten if you want to keep the originals.
