Hi all,
If I have a comma separated text file of the form:
filename.ext,thumbnail width,thumbnail height,img width,img height
for example:
inside3.jpg,100,75,640,480
over.jpg,100,75,640,480
stairs.jpg,100,64,640,410
tower.jpg,78,100,320,410
trellis.jpg,78,100,320,410
waterfall.jpg,100,75,640,480
then what is the best way to grab the next and previous images if I am
displaying, for example, "tower.jpg". (I'm using PHP, but I can work with perl
too.) Thanks!
