Picture Transfer Question

I just got my Pearl 8120, and my issue is when I transfer pics with the usb cable, I get an end result of 2 files. One of the pic, and one of a generic icon with the file name of the picture, which I am unable to delete. The only way I've found around this is to email the pics to my gmail account, and download the attachments, but I feel like I shouldn't have to do this.
Is it because I'm transferring them from a mac?
Any ideas?
I do have bluetooth enabled on my computer, but they aren't able to connect. I never had any issues with other phones connecting via bluetooth, so I'm not sure what I'm doing wrong.
