File extension / image resampling

[bebop]

Hello,

 

I hope you can help me because this piece of script is driving me mad.

 

This script reads a folder, should select files that are of image format - JPG and variants-of-extension, and re-samples & saves them into another folder for thumbnail view.

 

The problem with it is that it works for some jpeg files but not others - indiscriminately! So I have no clue what makes it work with some and not others (in the same folder!!).

 

Then, again - sometimes, if I change a file extension from say "JPEG" to "JPG" and re-run the script, it works on that file (and keeps ignoring the others).

 

If it's of any relevance, all the files come from the same source - the same digital camera.

 

Any clue why?

 

Also one more question if I may, do I need some sort of buffering - sometimes the folder might contain 50 pics (or more) that the script (if working properly) would have to work on...

 

Thank you so much in advance for your kind help!
