I want to create a background for a website of mine. The image should be able repeat seamlessly so the background can be scaled to any size.

For example, It should look like this site.

I have no knowledge in any image software besides MS paint.

So what software should I use to make something like that more easy? Does maybe gimp has a feature to make an image like this or some other free software?

Example result I want to create:

  • @EricShain I think I didnt described it very well what I want. I want the background, not the animated gifs. I mean that the background has like a pattern that loops. For example there is half a car on the left side and exactly on the other side is the other half so you can loop the picture to fill a large screen. Edit: Here is the background image of this site

  • Maybe the background-repeat: CSS option is what you're after – so the half car on the left "docks" to its couterpart on the right of the previous one? If you really want software instead, please specify what OS it should run on, at what your price margin is.

I recommend Paint.NET with the Seamless Helper Plugin (direct download). After installation of Paint.NET, you need to copy that DLL file to C:\Program Files\paint.net\Effects\SeamlessHelper.dll.

Here's how easy it is:

  1. Create a new picture with even pixel length. I use 200x200 px here.

  2. Draw something on the center horizontal and vertical lines, like so:

First result

  1. From the Effects menu, choose Seamless helper. The picture will then look like this:

Second result

  1. Go on painting.

Third result

  1. Repeat it on your Website

Final result
