Gallery Width limited to 500px

Could you post your site URL here, so I can have a look?

If you want it to remain private, you can also contact us via this contact form:

@rely28: The site is loading really slow for me and what I can see has a lot of other errors.

Could you try disabling all other plugins and see if the problem remains? If not, then activate one plugin at a time until it stops working as expected; the last plugin activated either is the source of the issue or is in conflict with something else.

@traumkommode: In addition to esmi’s advice, since we only wrote the Jetpack code, it might be wise to submit a thread to the “Tiled Galleries without Jetpack” author. He/she might be using Jetpack’s code or might have created their own solution.

Could you try this code, changing out the number for your preferred width?

Sure—there are different ways of doing it based on how your theme is coded. If the full-width template is a separate page template, you could add the same code in that template, changing the value. May want to change the priority too (e.g. add_filter('jetpack_content_width', 'bk_set_jetpack_width_full', 11); to ensure that it takes priority over the initial one.

If you do that, be sure to change the function name bk_set_jetpack_width to something else for the second instance so an error isn’t created for having two functions with the same name and update it in the add_filter call.

Cheers!

Somewhere in your theme’s template, there is likely some if statements that pull from that sidebar setting and determine something different to happen (a change in classes for the CSS to pick up on, etc).

Wherever your theme’s templates pull that option is likely the best spot for code like this.

More about add_filter is at the Codex: http://codex.wordpress.org/Function_Reference/add_filter

Basically, the 11 is the priority number of that particular filter. Without a number, it defaults to 10. Something at priority level 1 is filtered first, something at a higher number later.

So, for example, how Jetpack’s Sharing buttons at the end of a post work via an add_filter('the_content', "sharing_display', 19)
If you wanted to do something to the_content and have it happen before the Sharing buttons are added, you’d want to be sure to do it at a number lower than 18. If you want to do something later, you want a number higher.

In our code above, the initial code that I suggested for functions.php doesn’t have a number, so it defaults to 10. In your case, since you have something special that you want to apply only in certain cases, we want be completely sure that the full-width number is used instead in those specific cases. To do that, we add priority level 11.
