I am pretty sure it would recognize JPG/JPEG, What extension do your photos have?
I have a Samsung SmartTV UN55H6350AFXZA serial 1323K. I wanted to make up a thumb drive to insert into USB port on TV and show photos. Well I used a well know program and made a PhotoShow. With, I think the extension of photoshow. My TV couldn't recognize the files. So what file types will Samsung SmartTv recognize? Would someone want to recommend a good, preferably free program to do this? Thanks
