Q: My big problem is that I would like to change some of the image from time to time and can figure out how to do that without have to build a new 3D gallery.
I do save my projects as you suggest under part 6 on cu3ox.com (the .c3x file), but when I open that file again after a while, all the image are gone.
On your website it says that the project consists of the pictures I choose to put on my 3D image gallery.
Is there a solution to this or do I really have to make a whole new gallery just because I want to add or remove one Image?

A: Actually, project file stores settings of 3D galley only (transition effect, direction of rotation, delays, etc.) and doesn't store images. So, if your original images were deleted or moved into another folder, they couldn't be opened.

You can open .c3x file in any text editor (for example, Notepad), find following lines:

<Image>
<url>D:\Temp\images\image1.jpg</url>

<title>Image 1</title>

<description>Click here</description>
<effect>down</effect>
<segments>7</segments>

<targetlink>http://cu3ox.com/</targetlink>
<target>_blank</target>
</Image>

and edit path to your image in "url" line. When you'll specify correct path, image will be opened in application window.
