The Nokia 3155 has a 262144 colour display and supports colour graphics and logo files that you can transfer to and from your phone via your PC.
You can add images to the Nokia 3155 with MobiMB Mobile Media Browser or Logomanager Pro Suite .
Just download the software, connect your PC to your phone and you can add any suitable graphics file in a variety of formats just by dragging and dropping into the phone.
Most phones can use these files for a variety of things. Depending on the handset, MobiFX, MobiMB or Pro Suite are commonly used to change operator logos
(the graphic on the phone that shows instead of your provider name), startup/shutdown screens, wallpapers, screensavers,
and to transfer photos taken with the camera to and from the phone.
