Sorry it too so long in responding. I deleted the attempt, as I wasn't sure what it would do and didn't want to create a problem.
Basically, I went through the steps listed in how to upload a house (in this case a garden) to the Swap Shop. Went to the section of attachment then browse, Doc . . . Sim3Pack cut and pasted from the Showboat thread the pictures.
Went to preview to see how it looked and instead of a paperclip there was what you normall see, when you post the message box where it states standard and pick which ever one that fits your post.
What doesn't make sense is why didn't the paperclip show up? The photoes were there, and the attachment section looked as if it was filled in right (it matched where I had posted a previous garden). Tried it twice and same results.
The only thing that I could think of what was different, and it shouldn't have mattered, was that I had taken the photoes in sceenshots and set them in separate folders for each garden. Had used photoes for Showboat from that folder instead of the ones that appear in the screenshot group.
But that doesn't make sense, as they showed up fine on the Showboat thread.
I'm going to retry later today, maybe it was a glitch for that day. Had a lot going on over the weekend and did some work on another garden instead of trying to post that one.
