If you click on an image thumbnail on the edit page, you're shown a form for editing that image's properties (caption, licence, etc). One of the properties is weight - it determines the images order in slideshows, etc and should be a number. The image with the lowest weight is used for the project thumbnail, if more than one image has the same weight then it will depend on which one was added/edited most recently.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Thinking about it I should probably remove the weight field and have weight set the same way project sections do, with the little up and down arrows next to the section. More intuitive IMO. In that case the image at the top of the list will be the thumbnail, and new images will be added with incrementing weights, rather than the default (0). Does this solution work for everybody?

Ja, that solution sounds more useful for me. Let's try it out.
