I usually use a program called, "Irfanview" for photo resizing and editing.
I used Irfanview years ago but loving Photography I need something that would do no less than what can be done in the lab with film. Today, friends and Church Family Scan torn pics and email the file to me ad I completely restore and enlarge them and return the file for them to have professionally printed.
My favorite was a Deacon's grandfather and another man seated oon the crest of a mountain in North Carolina, playing cards with an unlabeled, long necked, clear bottle of clear liquid setting between that they, obviously were partaking of. It was on a 3.5x5 inch piece of Bak-o-Lite that had broken in half and over the years had lost about a quarter of an inch missing from each of the broken edges missing as well as about a third of the right B
The OP question has nothing to do with "some on these forums". Nothing.
You are new here and not very wise. After you come to learn

I restored it and bew it so it could be printed as large as 20x30" and ran off an 8x10 to give to his wife when I returned the original, the disk with the file and thhe 8x10 for hs birthday. She paid me fifty and 75 to a printer and gave him the whole lot, save the original for his birthday.
My second favorite was a 5x7" from the mid thirties of the nineteen hundreds of an old Pick-up Truck with eight Kids inside the bed with dad leaning on the tail gate. The infant in that one had had half of it's face cut off and it was and old B&W with the scroll work printed on the over-sized edges. I rebuilt the baby's face by Point to Point Selection, flipped it horizontally and I believe I rotated it about 7.5 degrees and moved it into place. when all of the Layer Work was finished I merged then and save it as a B&W. then i told the owner it would great in color if she could tell me which person had what color garment on. I Point by Point selected after bowing the image by 1300% and I painted
each arm, leg, face and garment while selected to prevent bleed over and painted the truck bright ref. The own did not have as nickel to her name but I printed it in both Color and B&W and when she saw the color 8x10 she cried and told me some silly nonsense and said her little sister would inherit the B&W.
I did all of my PhotoShop work with the Free GIMP Program but if you operate windoze make dead certian you download the package and any tools only from the official site. Running Open source of windows is frowned upon by windows nerds and many of the windoze versions are routinely infected but not on any of the Linux Group.
