.3G2, jpg pictures not working

I tried loading a .jpg picture and a couple of .3g2 videos onto my E280, and judging by the converter (it all worked from there, no failure messages or anything), they should have worked. But when tried to enlarge the jpg on the player it acts as if I’m trying to play a song (it shows the big icon that comes up when you dont have any album art, only larger, as well as a progress bar at the bottom, as if a song were playing). Then when I tried to play the videos, the same icon showed up, but the sound from the video played. Any ideas as to what’s going on here? I’m using the latest version of the converter and my firmware is up to date as well.

Thanks in advance for any help, and I apologize if this has been covered, but I’m off to bed and don’t really have time right now to scour through pages upon pages of search results.
