Hello and welcome,

Please check your formatting next time (that's what the preview button is for).

I don't know exactly what your question is, but here are some quick pointers:

Image resizing: you can use Image::Magick to scale images. Alternatively you can just resize an image in HTML using the width and height attributes of the IMG tag (ugly and slow, but it works).

As for the slide show: I'd just use something like:

print qq[<a href="show.cgi?image=$previd">previous</a>  <a href="show.
+cgi?image=$nextid">next</a>];
[download]

And get the $previd and $nextid form your database.
