Ok this is just plain odd, and I'm hoping someone has experienced this. On my iMac in my Picture Project directory in Finder, every picture's thumbnail that I have taken with my Nikon D50 has a black border around them. Now this border doesn't show up when I open the pictures, just on the thumbnail. Here is the even odder part, pictures that I have taken with another camera on the same memory card and in the same directory even do not have the black border, just the photos taken with the D50. (and yes the photos still defaultly open with Preview). I keep copies of these on my powerbook as well, and strangely enough this isn't happening on there, the thumbnails are normal and have no borders. The only new photo app that I have even used in the last few months is the Adobe Lightroom Beta (and when I used it, I only imported like 5 photos, and just now I added a downloaded photo but it did not change that photos thumbnail), is there anyone that has used that app and noticed the thumbnail border occurance(if it exists at all)? It's the only possibility I can think of but I haven't found any documentation that would prove Lightroom did it, and if lightroom did do it, why just my Nikon shots, why not the Canon or Samsung shots and why didn't it affect generic downloaded photos.
