Decoding a file name

[Arthurhh]

There is an image file produced on a local web site that i would like to grab on a regular basis. Getting permisiion is not the problem, but decoding how the generated file name is produced is.

http://www.XXXXXXX.XXX/IcePics/ob/7d73-12339d0fa40-12339d2dcdf.NPL.png
The Url is contstant but the hex sequence before the .NPL.png changes for each image, now I assumed it is a time date stamp but havnt worked out how it relates so I can predict the next images generated name.

below is several files with the date time stamp, can anyone see a relationship here, or know of a way to get the approiate next image.

I think that the figures betwen 7d73 and .NPL.png is the UNIX time stamp for that file.

I think that the figures betwen 7d73 and .NPL.png is the UNIX time stamp for that file.

That's what I figured so it is off to Google I go to work this out unless I can find some code that checks the directory for new files and downloads them, I can then use them by selection the english in the name plus the file date stamp.

Done the google thing and it is not a unix time stamp, unix epoch time stamps are decimal according to what I have found so far
