At 08:25 in this lesson, we are comparing the length of the string in the Imagesfolder to determine if we need to copy up to the server. What if we are in another folder on the server, with the length of the PathFilename identical to that of the ImagesFolder? Would that not create a problem?

Reply from Richard Rost:

It's not just the length we're checking... we're comparing the beginning of the folder string to see if it's identical to the same length of string from the chosen file. I did think of one problem, however. If you have your Images folder set to:

C:
Then any file you choose on the C:\ drive will show up as being in the Images folder for the purposes of this function. I suppose a better algorithm is needed. Until I have a few minutes to come up with one, just make sure your Images folder name is UNIQUE on your hard drive, like:

C:\Data\dbImages
Or something like that - something that's not going to be easily confused with another folder.
