is it necessary to use .png file format for images,
as both .jpg and .gif images work pretty fine.
also, another thing i noticed is the when i try to resize my image using a custom-made image resize function, i get an out of memory error.

According to the API, PNG is the only format that devices are required to support; if JPEG and GIF work it is only because that particular device happens to support them.

If you want your application to work on *all* devices that run J2ME, it is best to use PNG since the other formats might not work.

That is the correct answer. Nokia devices support JPEG and GIF within the J2ME runtime. But the spec does not guarantee that all devices would support those formats.
