Re: crc check for JPEG file exists

I would rather use md5_file() for file uniqueness.

hello

is crc32() an acceptable way of managing whether a JPEG file exists
(in a database or similar collection)?

i mean doing a crc32() on the binary data of the JPEG file, and then
check the database if there is already another entry with the same
CRC.

the database has relatively few images (some thousands).

is there any chance of collision (two different JPEG images generating
the same CRC) that is anywhere near likely, or is this extremely
remote?

advice would be appreciated.
