When viewing the images in Fullscreen-mode, the cursor and all other visible elements will disappear after 2 seconds.

This is great, but a mouse click does not stop disappearing at the moment. Also scrolling through the thumbnail-list does not prevent the hiding effect.

Perhaps it would be a good idea to add the Watermark (if the user decides to show one) image by image.

It't possible that the user want to show images from different sources, different watermarks would be needed than.

Another field in the Images-XML is necessary for that.

If the maxiMEE fullscreen mode runs, fast clicking can cause the program to crash.

I’ll try to bar nervous visitors (you know these people who can’t wait and start clicking around) from producing this type of error by:
- adding an overlay while a process is active
- hiding the mouse

I noticed, that from time to time (not reproducible), after deleting the browsers cache and opening maxiMEE for the first time, the intermediate image isn't loaded.

If you try to store images for the maxiMEE gallery under a root url differing from the one maxiMEE uses, Flash needs a cross-policy file on the remote server (storing the images).

For now this is NOT supportet.

Precaching of images happens only for thumbnails, after hovering the thumbnails-bar the first time.
maxiMEE loads all images in a row afterwards. I have to optimize that.

Large images aren't cached right now, still didn't decide if I'll change that.

This isn't a real task. You should close it and start opening some real tasks.
