By default, if you post an animaged image in Slack, it will automatically play–and some can be quite annoying. If you would rather not see every animated image play automatically, you can easily disable this feature.
默认情况下，如果您在Slack中发布一个经过图像处理的图像，它将自动播放-有些可能会很烦人。 如果您不想看到每个动画图像都自动播放，则可以轻松禁用此功能。
To prevent this, open the Slack app to any channel and tap the menu button in the upper-right corner of the screen.
为防止这种情况，请打开任意频道的Slack应用，然后点击屏幕右上角的菜单按钮。
Tap “Settings” on the menu.
点击菜单上的“设置”。
On the Settings screen, tap “Accessibility”.
在设置屏幕上，点击“辅助功能”。
Tap the “Disable Animated Images” slider button so it turns green. Now, animated images will not play automatically. They will display as static images.
点击“禁用动画图像”滑块按钮，使其变为绿色。 现在，动画图像将不会自动播放。 它们将显示为静态图像。
NOTE: Slack is set to automatically play animated images unless Reduce Motion is enabled in the iOS settings (General >Accessibility > Reduce Motion). If you had Reduce Motion on when this Slack feature was launched, Slack will have turned it on, and animated GIFs will not play. It does not appear that altering one of these settings affects the other after the fact, though.
注意：除非在iOS设置中启用了“ 降低运动” (“常规”>“辅助功能”>“降低运动”)，“松弛”设置为自动播放动画图像。 如果您在启动此Slack功能时启用了减少运动功能，则Slack将启用它，并且动画GIF将无法播放。 但是，事实证明，更改其中一个设置不会影响其他设置。
Unfortunately, with animated images disabled, GIFs turn into static images that cannot be played manually one at a time. If you want to see one animated image play, you must turn off the Disable Animated Image option and let all the animated images play. It’s either all or nothing. But, at least it’s easy to toggle this setting.
不幸的是，禁用动画图像后，GIF会变成静态图像，无法一次手动播放。 如果要观看一个动画图像播放，则必须关闭“禁用动画图像”选项，然后播放所有动画图像。 要么全有要么全无。 但是，至少很容易切换此设置。
