How do I make jpeg image background transparent?

[Creamlistner]

There are better ways >.>
If your using PS(photoshop) than heres how.
In your tool box there Is an eraser, If u right clikc It says "background eraser"
This will let u click on the white and It will turn It transparent.
If you have trouble with that, use the pen tool to outline the flower and copy and paste It onto a transparent doc.
Try this out and let me know how It goes.
Save as Png. Otherwise It dosent work, jpeg dosent do transparent =)
