Other way for preview images in manager?

I know there is a showImageTVs plugin and I used it until yesterday. Now I have a problem with that plugin because some CSS defs "overlay" the manager and I don’t know why. At first the background color in the right manager frame in edit mode is like the background color of the site’s CSS. Then, every time the frame refreshes by the plugin, TinyMCE flickers in the header with the icons. Deactivating the plugin (and only this plugin) solves the problem.

Now my question: is there another way to have preview image for image widget? For my clients it is more comfortable to see the chosen image and not only the image path in edit mode of a document. I think it must be an easy way to put a preview of chosen image to the image widget but I can’t see them. Any help/hints would be nice.

No ideas for an other solutions?

Nobody needs this but me? Or have I found a limit of modX? Can’t believe it.

Someone has implemented this in a plugin i believe.

Yes, it’s the ShowImageTVs plugin (said above) and this has some issues with CSS. I don’t know why. That’s why I’m searching another way to show the image or a thumbnail thereof of an image TV.
