No, that's not a major problem

Ive noticed antp that some of the images that I have captured before and are on the site have black lines on the side like the secret servise I dont think it matters

ive added the rest of death train

yes

Know thats better

Select the area to keep, then there is a "crop" command in one of the menus I think, then save as jpeg as you did before

how do I do that with xnview

Well, if you can it is also better to remove black borders (like the one on the left on that picture).

is there anything else that I would have to change

I installed xnview
