I have a number of photo's which are >7mb in size and I want to upload them online for a photobook. I have uploaded photo's of this size to numerous photobook sites before but this particular site for photobooks suggests reducing the size to 2-3mb otherwise the software will be very slow. I have compressed photo's of this size before in Microsoft picture manager (when I want to use them on my pc at work as screen savers but I haven't got much drive space) and they have looked ok on screen but will this affect the print quality? The largest size photo I would have in the photo book would be approx A4.
I don't really want to download any software to compress the photo's as I am always concerned about downloading things as I'm not very tech savvy! I could have downloaded software for this particular photobook site, which is suitable for large photo sizes, to use offline but again I was worried about downloading it! If I chose not to compress the photo's would it really take that long to upload them? Any answer or advice would be appreciated! Thanks!
