Do you not have Cpanel???, I guess this would be far the easiest to use when uploading files? With Styles you need to upload the images into the images directory of the style folder.
Many years ago i was uploading the images into the default style images and not the new style image folder, oftened wondered why my templates never came out good.
Your best bet would be getting someone that can help you from your board?? Someone that you can trust, with Server experiance, perhaps now the time to offer a super mod position, therefore helping you out also?
Good Luck :up:
