PlayStation 3 Custom Theme Guide
Step 1| How to Edit PlayStation 3 Theme Images
Note: If you just want to change Background image, then you do not need this guide, you just have to place desired image in “Pictures” folder and set it is as your Background.
You can customize images like your background, icons, pointers and even the notification Box using any image editor that you feel home at.
But, you need to edit the images with these specific rules in mind.
24 Background images can be included in a theme, each background image must be scaled as SD and HD sizes.
SD image size 640 x 480 JPEG
HD image size 1920 x 1080 JPEG
Maximum image size can only be 2MB.
While selecting your images as background, you must keep in mind that your icons would be readable.
Icons placed on the XMB bar of your PS3 can be modified.
Icons must be 128 x 128, 32-bit PNG with a transparent background and alpha channel enabled.
Some icons have special size, Size of default icon of photo file and photo folder is 170 x 128 and that of video file and video folder is 228 x 128.
Rename your icon image files as given in sample.xml like
Your notification box can be modified to make it compatible with you theme, image size for the notification box is 64 x 64 and should be 32-bit PNG with alpha channel enabled.

Now you just have to rename simple.xml to any name you desire for your theme, and edit values/filenames.
Note: Read carefully the “readme_e” file to get directions on how to complete the XML file.
