Just out of curiosity, do you have wordpress set to generate 460 x 400 thumbnails? (settings > media in wordpress).

If there’s issues with jpeg compression I think it’d be a wordpress problem and not an issue with this plug-in, I don’t think this plug-in is actually doing any thumbnail creation / jpeg compression.

(I changed, in the plug-in, my thumbnail dimensions to 300×300 and my images came out all pixelated– the problem was that it uses the default 150×150 thumbnail image that wordpress creates when I upload images, so it was just scaling the 150×150 up to 300×300, resulting in really crappy looking images. If I were you, I’d go into “settings > media” and set the thumbnail size to something equal to or higher than what you want the thumbnails to display at (that way you can scale down if needed but never worry about crappy resolution when scaling up.)

I haven’t tinkered with 400px+ thumbnails, so I don’t know if wordpress is by default using a higher amount of compression for thumbnail images.

I could be wrong, but here’s what I think is happening.

This plugin isn’t generating thumbnails, it’s using the thumbnails that wordpress creates when you upload an image (I discovered this because I changed the setting in this plugin to 300×300 and my images came out all pixelated– the reason being that it was scaling a 150×150 image– the default thumbnail size that wordpress generated an image for when I uploaded my images– up to 300×300).

What you need to do if you want your thumbnails a specific size is in WordPress, go to “settings > media” and change the thumbnail size to be the proportions / size you want. Note that this will only affect images that you upload after you change that setting (unless there’s another plug-in that can automatically go through your images and regenerate thumbnails.)

The “Thumbnails for Excerpts” plug-in can scale down that thumbnail to whatever size you want, but it’ll be the same proportions. If it forced your 150×150 thumbnail to 100×50, it’d be all distorted.

Hope this helps.

I just installed 2.8… Lightbox plug-in appears to no longer be working (I have Lightbox 2.8.2 installed). Deactivated the plug-in and reactivated it… no dice. =(
