Hi there

I’m having some issue with the quality of the portfolio thumbnails. They seem to be compressed down to 400 x 300 px automatically. I’m uploading them at least 1500px (where possible) as when you reduce the screensize they become full width at around 750px.

I’ve read the other posts in the forum but this did not help me.

Please can you advise where I can make the relevant changes?

Thanks

James

I’d need to see your link, it depends on how many columns etc you have set

Open up sf-portfolio.php in swift-framework/content and edit from line 360. Or if you’re using a child theme you can add the whole function to your child theme’s functions.php file:
