Additional shortcode options

For #1, you can specify this for the Justified Grid (Photonic → Settings → Layouts → Random Justified Gallery – Minimum Tile height). The setting will apply to all your galleries that have this layout. It is currently not possible to control this for individual galleries.

You cannot do #1 for Mosaic galleries, because mosaics behave differently. There is, however, a different option for Mosaics, Photonic → Settings → Layouts → Mosaic Layout – Trigger width, using which you can control when the mosaic layout should get triggered. This avoids showing tiny images for narrow layouts.

For #2, do you mean you want to show full sized images in the main layout, scaled to fit? For that you need the tile_size attribute. The Photonic wizard shows you this option.

Thank you for your lightning fast reply!
#1 – are you planning to add the Mosaic Trigger width and Random Tile height options for individual gallery shortcode?
#2 – tile_size option works perfectly, thanks!

It is a possibility, but given that users generally prefer a level of consistency for all their galleries, I have left the feature as it is for several years now (this feature was introduced in 2016). I might add it in the future, but it isn’t high on my to-do list for now.

I understand, no problem, thanks!

Another question, if you don’t mind. I print a gallery directly from a page-id-template like so:
<?php echo do_shortcode('[gallery category="200"]'); ?>
and everything goes fine, but as soon as I change it to
<?php echo do_shortcode('[gallery category="200" style="random"]'); ?>
I get a blank area instead of the page content.
Interesting that when if I’m moving a mouse over the blank area I can see the gallery links in the left bottom corner of the browser. The links open in a new page on click, as if the gallery plugin wasn’t there at all. The same Photonic code works fine inside the page.
Is there a way to print Photonic gallery using PHP or may be JS?

I found the cause of the problem, it was my mistake – I just forgot to load the footer in the page-php. Everything work fine now, sorry to bother you with trifles.

If your page has widget areas / blocks, you could always add a Photonic widget or block for this – you wouldn’t need the custom code.

Thanks for the tip!
I just trying to device a simple solution to print galleries on a page using dropdown where a user could select and see different attachment categories from my media library.
For now I coded a dropdown using JS, but still have no idea how to use it to change category value in shortcode.
I’m not sure if I should ask your advice on it in this topic though.

I know that some folks try to use accordion plugins for this. I recall a thread from at least 4-5 years back when someone commented about using ACF for this, but I might be wrong.

A rather radical suggestion would be to go to something like Flickr or SmugMug, which lets you have albums. You could use Photonic to show a bunch of albums together, on which you can click to show the photos therein.
