questions before I activate module re products and pricing

[militaryamy]

I am looking into using this module for my prestashop as I already have an Ebay shop - but first I have a few questions and if anyone can guide me I would be very grateful

1) I do not want to upload all my products - some items are not to be sold on ebay but only on my own website - is this possible with this module?

2) Due to ebay charges i want to charge more for my products on ebay or price the shipping seperately (even though shipping is free on my own website) is this possible?

3) The images on my website are small for speedy upload - will ebay reject them all and refuse to upload - or can i update them manually on Ebay ??

Would be very grateful for any help - taking baby steps into a brave new world of expansion here - fingers crossed
