Let's take a look at how that would be in pseudocode:

Read file "thumbcount.txt" to get previous number of files
Read directory "thumbnails" to get latest number of files
If thumbnails != thumbcount {
    Delete everything in thumbnails directory
    Recreate thumbnails

Get new list of thumbnails
For each thumbnail in thumbnails directory {
    Show thumbnail

Update thumbnail counter

Make sense? It is really not so hard, albeit in pseudocode currently.
