"I have tried to make grid smaller but that doesn't work.
I only used 3 images narrowed down the size of the images as much as possible and have used a DPI of 12, but it takes a long time before the slideshow starts."

You can either set the images at the pixel width/height you want in the image editor (photoshop, fireworks etc)
or
resize them down in the module settings

for example 900px x 300px @ 72ppi (pixels per inch) with the module image resize turned off



or

you can have an image say 1800px x 600px @ 72ppi with image resizze turned on and then resize the image in the settings to 900px x 300px

With the module settings they work left to right

As you select different options on the left - different setting options will now show in the tabs to the left

Thank you Paul for all your efforts.
This is the best result I can get for my homepage www.spireality.nl.
When I look back at this subject I made the wrong assumption that I had the latest version of Zentools. I thought I downloaded the latest version by clicking on the image of zentools in the module Zentools. So that's why I've got lost.

I have one final question. In making my website I though I came accross Easyblog, but now I cannot find it any more. Please advice.

Best regards,
Joan

Hi Joan,

Easyblog is a commercial extension sold by
stackideas.com/easyblog

Zentools2 does support it but easyblog does require a separate purchase

Easyblog is mentioned in documentation and zentools2 which was probably where you came across it

Cheers
Paul

I should also mention there is a coupon on your subscription profile for easyblog

Cheers
Paul
