My attempts to sell my item have failed because the photo that I try to attach "exceeds the maximum upload value". I am told that I have to make the picture smaller - but I have no idea how to do this.
Google gave me a method for compacting pictures - but then I could not find the compacted picture to attach to my sales advert. At 86, Ido not lewarn complicated procedures easily. Please help me sell my item - a very rare WW1 tank mask.!!
