Hello glenon, I'm no expert at USENET, however after reading your post i
decided to check out Outlook Express's "News" feature. Here is some advice:
1. Start up Outlook Express. You should see a bunch of newsgroups you
subscribed to, under your ISP name (mine is news.datemas.de and under that
i have rec.gardens as one of my subscribed newsgroups).

2. Right click the ISP name (mine is news.datemas.de) and then select
"Newsgroups..."

3. A box will pop up with a Title of "Newsgroup Subscriptions". There will
be a "All" tab next to "Subscribed". It's the default selected but just
make a mental note of that Tab; It contains all the newsgroups your ISP has
subscribed to. "rec.gardens" will be one item in this long list.

4. Look for "alt.binaries.pictures" within this list. You could use the
"Display newsgroups which contain:" Tab to search through and locate
"alt.binaries" quickly.

5. If it isn't there, then your ISP DOES NOT PROVIDE you with access to
alt.binaries, cheifly because of bandwidth constraints.

6. If you really need access then you'll have to buy per month access to
alt.binaries (news.datemas.de, ought to provide pay access). They provide
me with free access to USENET text only groups.

I would suggest that you just use: www.flickr.com - for picture posting.

BTW if you need help with USENET/Clients and similar type questions then
you can ask on "news.newusers.questions" since your particular question
may be construed as being off-topic on rec.gardens.

But that's very verbose *grin*
