I've had an ipad for a short time and one of the failings of its Safari browser is that it generally attempts to prevent uploads and downloads.
The main downloads folks may want to do from ukexpert are of photos. Thankfully it is ultra simple to download a photo from ukexpert with an ipad and Safari, even the full size original photo. Simply view it on screen and then hold your finger on it, and you will see an option to download it, and this works fine.
Photo uploads appear to simply be blocked by Safari. One option is to just do them later from your PC or Mac, where photos will normally be for you to work on them/store them anyway. Also, if you ever want to it is fine to simply email photos to us and we'll make them live for you. forums@ the usual ukexpert.co.uk will get them to us fine.
I just uploaded a test image though in the totally normal way by simply using a different browser to Safari. On the Apple App Store you can easily locate and download other browsers. I just tried one called ICab Mobile after reading some praise for it somewhere and indeed, uploads were just as simple as always.
The test image I uploaded is here: http://www.ukexpert.co.uk/photopost/...%20screen.html
To create that screenshot I simply pressed the two ipod buttons - home and sleep - at the same time, and that creates a capture of whatever is on the screen at that time.
Hope this info helps someone. It was new info to me so I thought I'd share it.
