Static web photo gallery generator wanted

[Chris Green]

I'm looking for a simple, efficient way to generate an HTML gallery
from a hierarchy of jpeg images.

I.e. I have a directory ~/pictures which contains quite a deep
hierarchy of sub-directories oranising my pictures organised as I
want them.  It's quite big, something like 30 thousand images which
total something over 50Gb.

I want a way to generate a web gallery with much smaller iamage files  
(e.g.  maximum image size something like 1024x1024) in a hierarchy
with simple HTML (or whatever) to make it navigable with a web
browser.  This is 'all on one system', not for export to the WWW, it
will just be displayed using the apache server on the same system.   

I also want to be able to select just a few images and generate a
gallery which will be possible to export to a web server.  This is for

showing people a few pictures by sending them a link in an E-Mail.


  
Currently I use Photofloat (https://git.zx2c4.com/PhotoFloat/about/)

which does a fair amount of what I want but I'm looking for something

better.  Photofloat's disadvantages (for me) are:-

    It puts all of its output in one directory, so for my whole
    hierarchy there are well over 100 thousand files in one directory.

    This makes some operations rather difficult and slow.

    As a result of the above it's also difficult to find the reduced
    size version of any particular image which I sometimes want to do

    for attaching to E-Mails etc. 

    The navigation controls while adequate could be better.

    It's not particularly easy to run Photofloat on a subset of my
    images, I've written a script to do it but the whole thing gets a

    bit messy.


So, any ideas for a relacement?
