“Retina” images not reliably used
-
There’s at least two bugs which are preventing use of proper, high-resolution images in galleries:
- If you “Force Original Thumbs” it always uses a reduced-resolution version of the image, never the original. So if your original is actually already specifically sized for use in the gallery, you get a lower-resolution, blurry version instead.
Similarly if you have WordPress’s default settings in play regarding high-resolution images, whereby it refuses to serve anything larger than 2,560 on a side, you’re limited by that too.
I wish there were an option to just use the actual, original images. - The “2x” thumbnail generation option doesn’t work most of the time. It looks like there’s some rounding error bugs inside the FooGallery plug-in. e.g. if the source image is 984×2200 and you set the gallery width to 492, FooGallery uses an ugly quarter-resolution version of the image (492×1100) rather than the full resolution.
If you reduce the gallery width to just under half the actual image width, e.g. 491 in the above example, then it does render a high[er]-quality version but it’s still slightly blurry because it’s slightly scaled down (e.g. to 982×2196 in the above example).
I can’t find any viable workaround for these issues. It looks like I’ll have to switch to a different plug-in. ??
