Mobile wallpaper - How to

Mobile wallpaper, like a mobile game, is a piece of content that is installed on mobile phones or other mobile devices, such as PDAs and portable music players, like the Apple iPod. A wallpaper is simply a graphic that is formatted to fit the screen of a digital device, whether it is a desktop computer or a portable device.

How To Make Your Own Cell Phone Wallpapers

Step 1 - Obtain Cell Phone wallpaper size
Firstly, the size of the screen varies from company and phone to phone. So, the first thing you must do is find the dimensions for your cellphone.
For a Motorola v400, the dimensions are (but not limited to):

176 width px ->
220 height px ^
Both are in pixels.

Step 2 - Modify the wallpaper accordingly

Locate a picture that you enjoy, modify it and do something creative with it...
Then crop the size to the above dimensions or whatever the displayable size of your phone's screen is.

Note:
Sometimes if a picture is a little smaller or bigger, some phones have the options to "stretch" the image and others to "tile" the image. When a image is stretched it fits to the entire screen but may appear pixilated. Now, when a picture is tiled, the pattern is repeated.
over and over again (which may look odd if the picture is not a texture or the works)

Step 3 - Apply the wallpaper on to your mobile phone.

How To Get Pictures on to your Cell

Firstly, this will not be a indebt solution manual for everyone, this will just guide you to the right direction, you must do most of the research your self to get this to work.
Here are some of the methods, one can try to get pictures on to their cell phones:

Data Transfer Cable

A data transfer cable connects from your computer to your cellphone and as you may have guessed it, the data is used to transfer pictures back and fourth.
Now...You can either purchase the company manufactured cables for $70, or "after-market" cables for a lot less, say $5.
I personally have used both of them and to tell you the truth there is NO difference what so ever, both work perfectly fine, and one saves you $65.
The thing most people forget after getting this cable is the 'software' you need some sort of software or drivers to be able to transfer the files back and fourth.
This you must research yourself, usually all the information is provided to you on the companies site (Motorola.net/Nokia.net, etc) for motorola's one can use: Motorola Phone Tools or (MPT)
To sum it up: The initial cost of this may be a bit higher then others but it ends up paying for itself, plus you can download games and ringtones with this too afterwards. Not to mention the quality and everything remains the same.

BlueTooth / Internet
You may use the bluetooth capabilities on your phone to download the files directly from the internet or your computer. Check to see if your phone has this, most of the newer, high-end phones have this. Secondly, alot of the phones are capable of going on the internet also (beware: the prices are usually very high) and to download a picture using this way may cost you around $0.03 by kilobyte or approximately $0.60 or more per picture.

Final Words: Bluetooth = good, Internet = may cost you alot.

Final words: Decent, fast and reliable solution but may cost a lot in the long run.

Camera
I am sure most of you have tried this, and I don't have to write in debt about this, this involves simply taking the camera on your phone (if you have one) and taking a picture of it straight from the screen, beware of monitors flicker rate ;)
