The free IrfanView has a browse mode. Left right arrow goes to previous next file. It is good to have generally as it has some basic image editing and conversion functions.
I have it, but have not used it often. I'm sure XnView has a similar function. It seems to have a built in batch processing capability for applying edits/changes to multiple files. It has been around quite awhile. One of the more popular freeware image viewers.
