I have tested with many phones. All 3rd MR and 3rd FP1 phones can show it. Some earlier 3rd FP2 phones such as 6320 can also show it. But some phones such as E52, E55, N86 can't display a simple html page with a small picture. It seems it does find the picture because no red icon display there. But just the JPG picture can't be displayed.
I really have no clue. Any ideas?
