thank you for this tutorial.
I have changed the header(logo) image without problems and also gone through this tutorial for additional changes according to size etc. However my header image still stays the same size as the original phpBB one. Somewhere the previous image size is being added to the img code inline. I have tried adding the new size in all different ways in the imageset in the Administration board as well as defining size in he css-sheets and overall_header.html.
And yes, I have cleared cache and checked several browsers that haven't shown the forum before.
Anyone out there knows what is wrong?
you probably have not refreshed the theme/imageset/template.
go to the admin panel, styles tab, on the left, chose imageset, on the right click refresh for your style.
do the same for the template and the theme.
refresh your browser,
