In the galery, find tab Thumbnail, what settings have you got in outer margin ??

The lower, the closer the pictures are together ......

I have 3% margin. The pictures are closer , but only horizontaly not vertical. How to solve this problem?

Hello Marek,

Unfortunately this space is always visible because it's automatically added to fit the content when you add a frame to the thumbnails. The only option would be or to have more thumbnails visible on a line or to add a frame so that there will be less whitespace.

If you require any further information, please feel free to write back.

Hello Claudio D.

The frames are nice, but if I do not like used frame? Is there any solution? If I make my own frame in .png how to add it to project, and how to make the frame it will fit to pictures?

Thanks :) 

Hello Marek,

You can make zour own frame and in the options where you see the abvailable frames on the part below you can choose to add your custom frame linking the png file to add.

The program resizes the frame according to the size of the thumnails. Use a square frame and use the transparency.

Let me know if it helps.
