Duplicate Album Covers On Mobile Device

I opened and edited all of my songs on my laptop with correct album art. I put my SD card back in my phone and every single song had the same album art. Confused, I put my SD card back in my computer and every song's album art was correct; every song had the right art. I've restarted my phone and computer multiple times. I originally saved the album art with version 2.54 and even tried re-saving every song with version 2.52 on my other computer. This is really annoying and I would be very grateful to anyone that could help.

Thank you in advance.

Do a search on your SD card for *.jpg and make sure you search hidden files and folders.

Some devices will look for external jpg files for album art before they look for embedded art.
