Thanks for the reply, Gulliver_69.
If the software were to use CRC or other types of hashes, the user will end up with many copies of the same image (perhaps each displaying slightly differently due to animation), don't you think so?
My suggestion takes into consideration that all images are saved once, so as to avoid as much redundancy as possible (1 file for 1 image). Helps to keep the chat log folders tidy
This isn't really a big issue, but I think would be a nice addition to MsgPlus!.
