             }
         }

        return data1;
    }
}

the result of print is 1,2,2. only the first image gets stored. i checked the images. i created a form inside the startapp method and appended every image into it. i was able to see them no problem. i didnt even have to cast the elements to Image (formx.append(data.elementAt(0));
shouldnt it be 1 2 3? shouldnt i b able to store all the images? the sizes are small. 326 by 92 dimensions.
i checked the size of data1. it downloaded all 3 images.
if i try to print the details of the rms, i only get details for the first pic. the second one doesnt even get store. how come?
these two classes arent my final version of course. i no it looks a bit ugly but im just putting everything together for you.

Thank you.

i figured id store soon as i got the image. this time it printed 1 2 then recordStorefullexception then 2 then recordStorefullexception
how did it get full? o.o

figured id do some research. one link said that emulator could be full. that didnt make sense. but then this link http://forums.netbeans.org/ntopic10720.html helped. it had instructions for me to follow. im running netbeans 6.9.1 i selected java tm micro edition then clicked on tools&extensions. but thts it. nothing was highlighted. selectable.

i got it to work. friend suggested i download wtk 2.5.2. it worked. same code. i had no idea sdk 3 was buggy o.o

that totally makes sense, your images are _just_ 125 Ko big, so it is likely that the maximum size for a record store is less than twice that. on many blackberry before 2008, the limit was 64Ko.
oh, and just a small good practice : never leave a catch block empty. never. ever.
and you should check the available size of the record store before entering data.
and you probably should not save images in RMS anyway
