Mine did that too the first couple times I tried to post. Somehow, it let me do it after I shut the browser and re-logged in. Maybe that'll work for you??
Most programs will give you an option using "save as" to compress the picture or use web format.
Another work around is to open the folder where your pictures are:
right click on the picture file
select "send to" and "mail recipient"
You'll be given a choice of "make all my pictures smaller" and "keep the original sizes" select the make smaller option.
Once the photos are attached to an email in outlook, you can right click and "save as" using a new file name. You don't want to overwrite the original file.
ok so I tried tried and tried, but i could not size down the pics, however I did get them posted on webshots.com
If you click on the link below you can view the pictures. Maybe someone who is more computer literate can take the pics from there and get them on this site. oh well....here is the link if anyone wants to see!
