Hi there Nauriel.
Unfortunately, to make banners, avatars and the like you will need image editing software. As far as I know there are no free services that you can permanently download to make these graphics, so you will probably have to buy something if you want to do your own graphics.
We all use various types of software to make our graphics, the most popular being Adobe's 'Photoshop' or 'Paintshop Pro' by Corel (formally Jasc). There are, of course, lots of others around but I don't really know about them. I use Paintshop Pro 8 (although this has been upgraded twice so others have version 9, while version X has just come out).
Photoshop is the best, but is vastly expensive. I have, however, noticed that Amazon (at least Amazon.co.uk.) still sells Paintshop Pro 8 at very reasonable prices - so you might be able to find an older version of either program at a good price if you hunt around.
However, You can download a trial version of both PSP and Photoshop, which you can use for 30 days for free. I did this with the latest Photoshop and had a lot of fun with it (once I'd worked out how to use it!). You can do this through Adobe or Corel's websites, and as long as you save any graphics made with them as Jpeg files, you won't lose them once the trial ends. But if you want something permanent, you will probably have to buy it.
Mind you, if all else fails, you could always pop over to the requests thread as there are loads of people there who will happily make a graphic for you.
Hope this helps.
