I can't find any instructions on how to post an image on this forum. I assume that I simply attach a file using the facility I see below this post for example. However what are the size limits? (both pixel dimensions and file size). Any preferred format? (jpg/tiff for example).
On other fora I've seen 'stickies' that explain these things but I'm afraid that I can't find the equivalent here. Said I was dumb didn't I.
