A:Answer It really depends on what kind of camera you are using, and how many megapixels it has. Also, what file type they are saved as, RAW image files take alot more space than Jpeg. See chart below. So, if you are using a 16 megapixel(MP) camera taking jpegs, averaging 8 megabytes(MB) each, there are 1024 MB in a gigabyte (GB), this is a 64 GB flash drive, 64x1024= 65536 (total MB), divided by your image size (8 MB) 65536/8=8,192. So approximately 8,000 photos at 16MP, 16,000 at 8MP. A LOT OF PHOTOS! There are other factors in image size but, I think I have gotten too technical as it is. :)
I hope this helps!
