Thumbnails in a different directory

[Intrus]

What i want is that the thumbnails are generated in another folder than the original picture:

For a pic in "<CPG_Root>/albums/folder_name/some_image.jpg"
to be created in, let's say: "<CPG_Root>/thumbnails/folder_name/thumb_some_image.jpg"

The reason of this is that i have 2 comp, an old one (FreeBSD server, i will name it: F) hosting all services: apache, mysql, etc.
And my main computer for data storage and general use (regular windows, i will name it W).

I don't want thumbnails to be created on W because i sometime view those pictures from W and storing all the pictures on F is not an option since it doesn't have that much diskspace (thumbnails are ok with size of 80px max and compression of 35 i get around 10KB-15KB per picture)

What i'm currently doing is sharing folders on W with read only rights and F mount them in a dedicated place named "<somewhere>/samba/<other_folders>" and i put a symlink in "<CPG_Root>/albums/" to "<somewhere>/samba/" so i can add pictures from the samba folder but i need the thumbnails to be generated somewhere else.

I've searched the forum but didn't find what i wanted (or i haven't well searched -_-) (the FAQ "custom thumnails" isn't what i need)

So i've done some quick (and probabldy dirty) hack (that work) on those files:

I haven't tested the functions in other modes; but for what i need, it works, no change of the databse structure, nor major change of the core. It could be easily (i think) implemented if other people find some use of it, otherwise, i'll just do change myself on future version for personal use. <_<
(and i hope i haven't forgot to mention other modification i have made...)

I thought i could change the "get_pic_url", but it behave in a weird way, like showing the full pic and not the thumbnail, or showing thumbnail and not the full pic... Maybe i'll dig in some more if i have some spare time...

Hum, i should read better the code, only need to change:
./addpic.php
./delete.php
./include/picmgmt.inc.php
./include/function.inc.php

in function.inc.php, only change get_pic_url

by adding/changing in the function

if ( $mode == "thumb" )
{
$thumb_path = "thumbnails/";
}

        return $thumb_path . $url_prefix[$pic_row['url_prefix']]. path2url($pic_row['filepath']. $pic_prefix[$mode]. $pic_row['filename']);



it give a lot less modifications to do and less problem -_-

Are you contributing this as a hack? If so, we can move accordingly.

Or is this a feature request? I'm not sure of the benefit of this for many other users since this would increase the number of folders in their accounts. However, I'm sure there are those who would appreciate this as a hack.

[Intrus]

Well, i thought it could be implemented as an option in CPG, so if someone needed this feature, they just need to fill in the form in the configuration menu.

But if you feel like it should be in the hack section, please do so.

I was just wondering if anyone could verify if this is working in CPG1.5x?
I know the post is old, but this is exactly what I would like to do when I upgrade from 1.4 to 1.5
(Unless this can be accomplished in a better way now. . .)

Thank You !

Hi,
this would be a very interesting feature for the gallery. It permit to decide where to have the full size pictures and the thumbnails.
In my case I already have about 190Gb of images saved on the server. They are already sorted in folders.I used symlink to redirect the album folder to my server picture folder.
But I don't want this pictures and/or folders to be modified by other programs. So I don't want that the thumbnails will be generated on the same folders.
Allowing to choose the thumbnails and middle format folder would be a very good feature.
Will be this feature implemented?

Regard

Gian Carlo

We cannot implement this feature in the cpg1.5.x stage, so if it will be implemented it will take some time until the next major version will be released.
