I bet this these are questions that have come up before, because they've been happening to me ever since I first used Paint.net some 4 - 5 years ago.
There are two anomolies.....
I sell on eBay and take photos of items for sale. I use the photo editor to crop the pictures and also to reduce the size in the process - it takes a lifetime to upload a 12Mg photo onto eBay!
However, quite often, I find that the saved photo appears the same size as the original - it doesn't show the cropped close-up.
However, when I click on it, it does......
And there's a further related strange effect.
If I'm editing a whole series of photos, quite often the photo, when saved back on my computer, will show a different picture.
But again, when I click on it, the correct photo appears.
Usually the picture is the next one in the series - but not always.
Please can someone solve these problems for me.
PS In case anyone wonders why I haven't raised the matter before - well, it's like most things - you get used to it....! :?
