Linked to site - awaiting your advice - much appreciated

Hi there
When is a good time to get the code?

Nooo! The link to your site...

Sorry about my confusion. The site link is:

Many thanks.
Trevor

Any progress with the code for this change - really keen to finalize and publish my site.
Appreciate any help you can give me.

Sorry to pester you, but I really need to get this site published asap now - hope you can help me

You can edit the height in the functions.php... I was going to give you a code... but it looked funky... just edit the size of the slider add_image_size('content-slider', 455, 540, true);

or whatever page template you are using

"Full Width Slide images are resized to: 1600x540, Content Slide images are resized to: 455x540, Simple Slider images are resized to: 940x340"

Thanks. Have made that change, but no visual change to slider images. Do I also need to change settings in the anythingslider.css ? If so, where and how do I get to the CSS files .

Did you re-upload the pics?

You will need to re-upload photos after making the change to your functions.php file. In addition you will need to modify the css here:
/css/anythingslider.css

Anything with a height of 540px. Note: This is a customization and we cannot support that. These are pretty thorough directions though as there isn't much more.

Have updated functions.php, anythingslider.css and re-uploaded images.
This has successfully resized the height of the slider, and cropped the images to fit the reduced height, but the images are still being auto scaled to 560px height before cropping to new 350px height.
Have I missed a step or is there a way of turning off the auto scaling and cropping as my pictures are all saved at correct 350px height.

Note: This is a customization and we cannot support that. Feel free to contact us via e-mail if you want to hire us for help.
