How to clear the cache from a snippests

Hello
I create a snippets which will check if an image exists on a folder.
I also have a different page, from which I can add a image or delete.

When I visit my web page it displays the image. But when I delete that image, MODx keep in this cache the image and then I have error image becaise the src="" can not find it.

After saving my snippests, I discovered that the error disappear, and I also notice when I uncheck the option "delete the cache, when saving", of my snippests, the proble remind,

Then, I deducted that there is a caching problem.

Is there a way to clear the cache, throuh my snippsts when the image is not found?

Many thank for your help

[[!mySnippets? &page=3]]

I add a ! after [[
