Thumbnails are generated for my media uploads (they display in the authoring environment Items page and Media page as well as in the front end in the “Media list” block on item pages), but they don’t display in the “Media embeds” block on item pages (I just see the default square image.png icon with mountain and sun) nor do they display on the Metadata tab for each Media in the authoring environment (shows the same square image.png). Any ideas?
So, where exactly do they show and where do they not?
Do they show on the admin-side browse pages for the items? For the media? The public-side ones?
It almost sounds like you aren’t getting thumbnails generated but you’re setting custom thumbnails, but that doesn’t totally match your description.
Hi, no I’m not setting custom thumbnails. The thumbnails are being generated from the primary media via ImageMagic. It looks like I found the culprit, it’s the “Image Server” module, specifically “Default display of images” in the site settings. When you choose “original” as the value but don’t have a Universal Viewer block on the page (instead using “Media embeds” block) then the image(s) will show as those default thumbnails rather than displaying the originals.
When the value of “Default display of images” is “large” then the image(s) will show as expected. When the value is “tile” the image(s) will show up in openseadragon viewer(s). And when the value is “original”, the image(s) will show as default thumbnail icon(s).
Hmm, I can’t really give much information about the Image Server module, but that’s somewhat odd that the “original” option doesn’t seem to work well for you.
Maybe the images you’re using are of a format where the originals aren’t renderable by the browser (like tiff or jpeg2000)? There are also possibilities to create media where you don’t have the original file at all, but I don’t think that really matches your description.
