First, unless you have absolutely nothing of value on your laptop, including any financial info, personal info, or doing financial transactions (I.E. BillPay) you need to upgrade to this century. Using WIn7 on the internet is a big security risk.
Second, disk space and server space cost money. That said most home ISP accounts provide a free web server space as part of their internet package. You can use that, up to the limits of storage they provide, to host pictures, post the URL and they will display in the threads.
Third, I can increase the storage available to members, but I have to buy additional disk space from my site ISP. I have talked about doing this in the past but when it came time for people to pay no one stepped up. And it is not cost effective for me to do for just couple members. That said I more than happy to revisit the topic.
Last, another possibility is get your own web site hosting account. Pair.com, the host I use, has an account with 15GB of storage, 75GB of monthly transfers for $72.00 a year. You have full control, no popup ads or any of the other BS you typically run across. If this sounds interesting PM me as I think they have a referral program which may bring the price down.
As PA says nothing is free (except the free storage you get here for posting pics ?) Lots of alternatives PB, but the catch is usually those organizations don't want to host images that get posted to other sites.
