Preview image for each album

Hi Erwin,

When you set "Source" option to "Dynamic", the module will display any (showtime) custom fields of the currently viewed article.
Let's say you have an article named "Sample Article" which has a Showtime Image Gallery custom field. When you visit that article the module will display its gallery as far as it is published in an active position.

Regarding your first question, yes it is possible to have only the first thumbnail displayed but there is no option for this at the moment.
You need to either create a layout override or just use CSS. In both cases you just need to hide all image elements except the first one.
The CSS implementation should be something like this:

.your-module-class .showtime-image img {display:none}
.your-module-class .showtime-image:first-child img {display:inline}

Note that the above code should work for specific gallery layouts only. For some others you may need to use the layout override approach.

Please let me know if you need more help with this.

Regards
