Thank you! I used the plugin and the images show in the right size now.
This question is now completely answered.
I’d like to ask you one other question which also fits the title of this topic.
Is it possible to place a Text widget on the left of the slider? I noticed that this amazing theme has got Home Feature 1 & 2. That would be perfect. Is it possible to place the Slider widget in one of those Home Features so I can put a Text widget next to the slider? And maybe also change the two widget areas so that the slider takes about sixty five percent of the width and the remaining width goes to the text. Or maybe you’ve got a better solution for this. Also what do I need to do to change the size of the slider to fit into that widget area?
Thank you in advance!
