loaded jpegs from computer to 2g sd card loaded 2gb sd card into phone tried to wiew jpegs on phone says file too large, then black screen on phone

How big were the jpeg files? Maybe your phone can only handle smaller ones, the kind a camera phone might take. My 2 megapixel camera phone takes about 120 K pics. Or there might be a problem with the formatting. You should probably format the card while it's in the phone and not on the PC.

Photo file size: 2435244 B (resolution 0*0)(.jpg) Downloaded from *camera to sd card. Installed sd card into phone. Tried to view photo, message says file too large. Photo size: 71198 B (resolution 800*600)(.jpg) downloaded from *computer to sd card. Phone shows picture fine. Where is the cutoff for size? Can photos from *camera be downsized some way for viewing on phone? Can't find any info on phone. Motorola EM326G (NetTen Techs useless)

I don't know what the cutoff would be. Might be different for different phones. The specs on mine describe the screen as 262K TFT. The TFT is the method transistors are implanted in the screen but I'm not sure what the 262K means. Maybe it's the maximum file size--262 KB--or maybe it's something else altogether. With photo editing software you can decrease the file size. I haven't done it so I can't give specifics
