I wanted a cuter and more vibrant looking twitter background and the existing "FREE" twitter backgrounds just don't cut it. So i googled : "Creating my own twitter background and I found this website:  
Your Own Twitter Background



I created my twitter background with this size :
Resolution 1480×800


The regular sizes are :
Resolution 1024×768
Resolution 1280×800

However, these sizes do not fit into my macbook pro and I also wanted a more seamless twitter background design. 

So if you are using a 17inch macbook pro, 1480×800 is the right size.


Click on your photoshop icon, I am using CS5. Choose the photos that you want displayed on your twitter background.






Then Click on FILE>NEW



A pop-up menu occurs, WIDTH should be changed to 1480 pixels. HEIGHT should be changed to 800 pixels. 72 DPI.






For the main background layout, I used a rainbow gradient.
CLICK GRADIENT>CHOOSE COLOR>
STRETCH ACROSS THE BACKGROUND AREA.





The rainbow gradient was not pastel enough and therefore I blended it in.
CLICK LAYER>LAYER STYLE>BLENDING OPTIONS.
I changed the blending to be about 40%.






The rainbow gradient turned to this pastel shade.
I added my photo, my blog address and little did I know that
I had typed in a pornographic website add instead of my own.
FML..... ( yaya I very stupid.)
So ensure you check on your photo etc before the next step. 




After you are done checking, Click on LAYER>FLATTEN IMAGE.




After flattening the image, it would look like this. I haven't realised my mistake even at this point.
I only found out about the pornographic site when I showed the layout to my friend. =p




Realised that I had made a mistake and I replace it with a ribbon and typed in the
correct blog address : www.babelicious-me.com





After you done with the background, login to your twitter account, 
click on SETTINGS>DESIGN>CHANGE BACKGROUND IMAGE.
Upload your new background. 
AND There you go.... Enjoy~ =)
