Blurry thumbnails

Just for fun, I enabled 2x Retina images, and although there are NO @2x image files in the Media Library, this is what apparently fixed the problem!

hi @wpress2010

Glad you managed to solve the problem. FooGallery generates the retina images that are needed.

I figured that out! Not intuitive, though: perhaps you could add a note in the UI with the Retina checkbox that mentioned that FG generates the Retina images.

@wpress2010 Thx man, had the same problem. Thumbnails look much better after I ticked retina boxes.

Yup. Since FooGallery will generate the extra-res thumbnail images, maybe the Retina feature should be “on” by default.

WordPress, of course, generates all of the additional image file sizes it needs from the largest original file you upload. But Retina resolution images, AFAIK, all need to be generated with the @2x type of suffix appended to the original filename. So, what FG is going is taking f’rinstance, a file named “myimage.jpg” and using it create a thumbnail (i.e. smaller size) file, doubling the thumbnail size, and then appending the suffix, like this:

Original file, myimage.jpg = 600×800 px
Thumbnail of same file, myimage-150.jpg, 150×200px (what WP would create…)
Retina 2x file, 300×400px, [email protected] (FG creates this)

Not intuitive, like I said – but really nice, as thumbnails are very sharp.
