When making a website how can you make your background move or change pictures.

Well, i can help you, but please, after words, in the comments section, please tell me what website you used to make that website. All sites are different. Usually, when creating a website, search the whole page for some button that can allow you to upload photos/ images, and then, after this step, you can see that around your selected image, there will be colored arrows, or icons in general to allow you to move, expand, and flip your picture. There must Always, ALWAYS be an option to do that, look closer, i bet you can find something. also, tell me what site you used, or give me a link (a.k.a; weebly) so i can tell you exact steps. Hope this helps i really need the points!

I don't know if this helps in your case but when creating a website in you case I am guessing you are using html if you look up some basic tutorials on java script (which is for features which you are looking for) it will show you help to link JavaScript and html to make a flawless professional looking webpage

Would it be data software?
