Hi Flamedodger!
Im from Denmark, so I hope you can understand my explenation and spelling…..
I have a windows pc and I made the pictures with the free program pixlr.com/editor
Here is what worked for me……….
The slides:
I made a white box in pixlr that was 300 px high and then the width ajusted it self. Then I made a pic that was 200 px high (and the width ajusted it self) and put in the boks.
The “featured areas”:
I found that it was 480 px width and 200 px high.
I made a white box in that size and put in a pic that was 180 px high (and the width was ajusted by it self).
If you find out how to change the text in the “read more” button (I want it to be danish, please let me know! ??
