My set, Link's Unsorted Cards, is showing only Blind Tunneler, Gale Dancer, Leyline of Accumulation, and Yruné, of the Five Faces in the visual spoiler. I don't think that I accidentally changed the cardset options or anything.

Oh! This is one of the new features I rolled out a couple of days ago. If a set is large enough, the visual spoiler will be spread across multiple pages. It now sorts them by colour, and colourless cards are first. So it's showing you all your colourless cards. You can click the colour boxes for other colours to see their sections of the visual spoiler. If there are more than 50 within a category, they'll be split across multiple pages in the usual way.

Maybe I should have drawn people's attention to it a bit better. Sorry for the confusion. On the plus side, we should get far less downtime now from bots loading the visual spoiler for giant sets like Multiverse Design Challenge.

Oh. Now I feel dumb. I'll have to start using Cardlist to scan over all of my cards now.

Ah, yeah, sorry. Generating visual spoilers for the whole cardset at once just takes too long once a cardset gets big enough: it causes timeouts all over the place.

Hmm. That's a shame, contact sheets are a nice final step. Perhaps give it as an optional link on the visual page, but only if you're logged in (to prevent bots)?

Also - with the speedup of cached card preview - is it still too slow?

Individual card previews are very fast. Generating a whole VS I suspect will definitely not be. (Though I guess I could check.)

You're right, it would be nice to have some special link to generate an all-in-one visual spoiler of a whole set. (I think the cutoff is 275 cards, though, so cardsets of normal size will still fit on one page.) I ought to be able to prevent bots from doing it in one of a couple of ways.

Oh... hmm. Now that I've got separate cache fragments for each page of a visual spoiler, I could probably assemble a page that will make the client send Ajax requests for each section of the VS in turn. So the server load (if those pages aren't cached) will never be more than 50 cards at a time, so other users won't be slowed down much; but the client will gradually assemble a full VS. And if those pages are cached, it'll do it pretty quickly. Hmm. Yes.
